There are far better and shorter ways than this one, but I'm hoping this will allow you to see what's happening. If I understand you correctly, you want to extract the number in the input that has the highest 'count'. If so:

#!/usr/bin/perl
use strict;
use warnings;

my @data = qw(2 3 3 3 5 7 8 12 32 44 55 12 3 23 43 33 1 4 25 43 42 1 4
+ 5 3 3 3);
my %seen;

for my $num (@data){
    $seen{$num}++;
}

my @keys = sort {$seen{$b} <=> $seen{$a}} keys %seen;

my $highest = $keys[0];
my $count = $seen{$keys[0]};

print "Highest count: $highest, Count: $count\n";

[download]

It defines an idiomatic %seen hash for keeping track, and using each value in the data, sets the key as the number in data, and adds one to the current value. Then, we create a keys array with a backwards sort which populates the array with the data number that has the highest value (count) to lowest. We then set the count value to $count and the key (data number) to $highest.

If I misunderstood what you need, just clarify.
