When I do string comparisons in perl the strings seem to ignore the

I want to sort strings assuming the 'dictionary' order of the chars is
ASCII order: hypen, 0-9, A-Z.
It appears linux sort also has the problem (LC_ALL is blank).
Any ideas? I want to avoid a brute force char by char sort if
possible.

Please provide an *example* of your data, what it would look like if
sorted "properly", and what it actually looks like after being sorted.

unsorted:
22
2-2
2-3
23
21

linux sort produces:
21
22
2-2
23
2-3

desired sort:
2-2
2-3
21
22
23

It appears to work in Perl:

$ perl -le'@x = qw[22 2-2 2-3 23 21]; print for sort @x'
2-2
2-3
21
22
23
