List counting in perl

This code counts the number of rows with each new value in column three of my data

#!/usr/bin/perl
use strict;
use warnings;
open M,"<master.vim" or die "master.vim $!";
my %c;

 /^101,(\d+)/ &&  $c{$1}++ while <M>;

close M;
open C,">count.txt" or die "count.txt $!";
print C "$c{$_}\n" for sort{$c{$b}<=>$c{$a}}keys %c;
close C;

Could the code be altered to do the same thing, but for the fourth column ?
