The general reason you are having problems is that you are trying to sort both the hashes and the filenames, as if they were equivalent items. They aren't: They are related.

This calls for a Perl hash, which keeps related things together.

I've been trying to adapt one into your code for five minutes or so, and have come to the conclusion that either I don't understand line 3, or there is something completely screwy with your code snippit.

Therefore, pseudo-code to do what you want:

my %file_hashes;

foreach my $file ( #List_of_files ) {
    my $hash = hash_fuc($file);
    $file_hashes{$hash} = $file;
}

foreach my $hash ( sort keys %file_hashes ) {
    print "$hash $file_hashes{$hash}\n";
}

You'll probably want to read up on hashes in Perl. They are useful.
