You mean, besides putting the files out there with sort-appropriate names?
I'd build a dictionary of names specific to the requirements then sort it.
eg, make it look like:

>>> d = {('f',1):'f1.dat', ('f',2):'f2.dat', ('f',100):'f100.dat'}

then:

>>> ds = d.items()
>>> ds.sort()
>>> for k,d in ds: print d

f1.dat
f2.dat
f100.dat
>>>


HTH,
