@Anastasia: Then make results be an OrderedDict. Change results[key].append(value) to results.setdefault(key, []).append(value).

Also, the names of variables are words, they don't end with a number, so I can't simply re-order the file based on the numerical value.

No need to guard key = key.split('_')[0] with if '_' in key: because "nounderscore" == "nounderscore".split('_')[0].

@Anastasia: No need to sort the result. collections.OrderedDict preserves the insertion order of keys.
