I don't see any problem here. You just need to distinguish between
strings and values on sorting:
a. 00 -> value 0
b. 0b -> value 0, followed by string "b"
c. 01 -> value 1
d. 1 -> value 1

so while the strcmp() is the tie-breaker between c. and d., sorting
of a. and b. is also rather simple -- you sort by the leading numbers
first. This makes a. and b. come before the others. Then, as a. and b.
are a "starting with zero"-group you have to resort that again as
there is a tie with the numbers. Thus b. comes after a. That's how
ASCII-sorting would do it (and also how windows explorer does it).

You can't simply sort by leading numbers and ignore that the string
has other characters in it too.
