in reply to Sorting hash of hashes by values

You're almost there, just change the print statement to:
print "$value -> $key\n";
If all of the values are numeric you should change the comparison operator to <=> like so:
foreach my $key (sort { $HoH{0}{$a} <=> $HoH{0}{$b} } keys %{$HoH{0}} +) { my $value = $HoH{0}{$key}; print "$value -> $key\n"; }
