Climbing scoring puzzle inspired by today's olympic event

Question

Necessary information. The sport climbing consists of three disciplines: speed climbing, bouldering, and lead climbing. In combined events, the disciplines come in this order, and the combined score of an athlete is a product of his/her standings in all three disciplines—with the lowest score ranking higher. In case if equality of the scores, the qualifications standings are compared.

Say, athlete A finished 2nd in speed, 5th in bouldering, and 6th in lead, athlete B, 4th in speed, 3rd in bouldering, and 5th in lead, athlete C, 3rd in speed, 6th in bouldering, 4th in lead. Then the combined score of A is $2\times 5\times 6 = 60$, the score of B is $4\times 3\times 5 = 60$, and the score of C is $3\times 6\times 4 = 72$. So the athlete C will rank lower than A and B, and among those two, the one who ranked higher in the qualification for the event will rank higher in the event as well.

Now here is the puzzle (assume that there can never be ties in any discipline).

DISCLAIMER The story, all names, characters, and incidents portrayed in this post are fictitious. No identification with actual persons (living or deceased) is intended or should be inferred.

Eight athletes—Adam, Bessa, Colin, Daniel, Fedir, Guillaume, Hannes, and Jacob—take part in a climbing combined final; their qualification stangings are in the reverse alphabetical order. All athletes have already finished all their attempts with only Jacob left to climb the lead route. It appears that:

• each of the athletes may get a medal (rank first, second or third) in the combined event, depending on Jacob's rank in the lead climbing;
• none of the atheles is guaranteed to get a medal;
• the eight possible medal-stand trios are different.

What are the atheles' ranks in all three disciplines?

I hope the question is clear (please feel free to ask if it's not). So far I managed to find one solution, but there might be more.

Answer 1

Here is a solution found using Z3 (python code here):

Athlete	Speed Ranking	Bouldering Ranking	Lead Ranking
Adam	8	6	1
Bessa	6	4	2
Colin	3	5	3
Daniel	5	2	4
Fedir	1	8	5
Guillaume	7	1	6
Hannes	2	3	7
Jacob	4	7	-

And here are the possible scores, with the medal-winners highlighted:

Jacob's Rank	Adam	Bessa	Colin	Daniel	Fedir	Guillaume	Hannes	Jacob
1	96	72	60	50	48	49	48	28
2	48	72	60	50	48	49	48	56
3	48	48	60	50	48	49	48	84
4	48	48	45	50	48	49	48	112
5	48	48	45	40	48	49	48	140
6	48	48	45	40	40	49	48	168
7	48	48	45	40	40	42	48	196
8	48	48	45	40	40	42	42	224

Answer 2

Here is my solution (found manually):

Athlete	Speed Ranking	Bouldering Ranking	Lead Ranking
Adam	2	4	5
Bessa	8	3	2
Colin	3	5	3
Daniel	7	1	6
Fedir	1	6	7
Guillaume	6	8	1
Hannes	5	2	4
Jacob	4	7	-

The final scores:

Jacob's Rank	Adam	Bessa	Colin	Daniel	Fedir	Guillaume	Hannes	Jacob
1	48	72	60	49	48	96	50	28
2	48	72	60	49	48	48	50	56
3	48	48	60	49	48	48	50	84
4	48	48	45	49	48	48	50	112
5	48	48	45	49	48	48	40	140
6	40	48	45	49	48	48	40	168
7	40	48	45	42	48	48	40	196
8	40	48	45	42	42	48	40	224

What is interesting is that while the solution is essentially different from @2012rcampion's, the second table is the same (up to permutation of athletes).

My solution has an additional peculiarity (which is also possible to achieve with @2012rcampion's solution by permuting athletes):

• One of the athletes except Jacob (here, Guillaume) may place first and last.
