hi all,
here is the final code 

use strict;
open(SORT_FILE, '<', "sort_test.txt")
            or die("open failed: $!");
my @to_sort = <SORT_FILE>;

my @from_sort = map { $_->[0] } 
                sort { $a->[2] <=> $b->[2] }     
                map {[$_, (split /CF|\./) ]} @to_sort;

foreach my $sorted (@from_sort) {
    print $sorted;
}

my $idx=1;$idx++ while ($idx < @from_sort) and substr($from_sort[$idx]
+,41,4)-substr($from_sort[$idx-1],41,4) <=50;
my @sort_splice = splice @from_sort, 0, $idx;
my @sorted = (@from_sort, @sort_splice);
