Hi, I really don't understand what you want but from, your desired output, I suppose you want to sort your files in the directory which has the same names ( about three files names with different date tags ), but different date tag.
Then get the latest of these files based on the date.
If an right, this is one way of doing that.

use warnings;
use strict;

my %report = map { $_->[2] => $_->[0] }
            sort {
                   $a->[1] <=> $b->[1] 
                         || 
                   $b->[2] <=> $a->[2]
                 }
            map { [ $_, /^(\d+?)\/.+\/(\d+?)\./ ] } <DATA>;

print $report{$_}, $/ for reverse keys %report;
