This solves the core of the problem, but is not quite there ;-).
Thomas requested conversion of int literals to ints, which is easy:

import re
s = 'si_pos_99_rep_1_0.ita'
res = re.split(r'(\d+)', s)
for i,s in enumerate(res):
   try: res[i] = int(s)
   except: pass
res = tuple(res)
print(res)

('si_pos_', 99, '_rep_', 1, '_', 0, '.ita')
