This code works with the numerics: 
use strict;
use warnings;

my @names;
my @numerics;
my $rec = 0;
while (<DATA>){
   ($names[$rec], $numerics[$rec]) = split /:\s/,$_;
   $rec++;
}

for (sort {$numerics[$a] <=> $numerics[$b]} 0..$#numerics){
  print "$names[$_]\n";
}

Note - I got rid of the terminating " ." which interfers with the "number" to the right of the ":".

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
