The second foreach could become:
foreach my $ec (
sort { $RNC{$frameNo}{$a} <=> $RNC{$frameNo}{$b} }
keys %{ $RNC{$frameNo} }
) {
....
}
(If you want to swap the sort order, just swap the $a and $b round.)
(For what it's worth, I tend to use "for" instead of "foreach" as I
think it reads better, but either way will work.)
