Realize that all hash keys are strings.
sort { $hash_fin{$b} <=> $hash_fin{$a} } keys %hash_fin
You were almost there:
sort { $b <=> $a } keys %hash_fin
The <=> operator is numeric, so casts it

Data::Dumper can be configured through the use of its package
variables (or methods if you are using the OO version). For instance:

You need to do:
[code]
my @keys = sort { $a cmp $b } keys(%hash);
[/code]
Is it causing a memory overflow?

Thanks for all who helped with my Perl coding,
I thought some folks here might benefit from me posting the final
code I used on a current project:
---snip---
if ($sort_order == 1) {
# sort by name (front part of the key)
foreach my $key (sort {lc($a) cmp lc($b)} keys %index){
&print_ta

Use of keys, map and sort (untested)
foreach my $subject (sort {lc($a) cmp lc($b)} map {[ $_, $subjects{$_}]}
keys %subjects){
printf "%-40s: %-s\n", $subjects{$subject->[0]}, $subject->[0];
}
Wags ;)
