We might be looking at it differently (me being the novice!), but doing this I organize it, however, the dates will change, so it seems to only group by the last number, not by the date as well. See how all 9's and all 10's, etc, will be grouped, regardless of the prior date. That is critical or the logs will be useless 

foreach (@files) {
my $file = $_;

my @newfiles = map { $_->[0] }
  sort { $a->[1] <=> $b->[1] }
  map { [ $_, /.+?-(\d+)\..+$/ ] } @files;

print $_,$/ for @newfiles;

outputs for example:
abcd1_abc_123456.abc1a_A.201307282200-2300-9.gz
abcd1_abc_123456.abc1a_A.201307282300-2400-9.gz
abcd1_abc_123456.abc1a_A.201307272100-2200-10.gz
abcd1_abc_123456.abc1a_A.201307281900-2000-10.gz

I need it to output like this: 
abcd1_abc_123456.abc1a_A.201307282200-2300-1.gz
abcd1_abc_123456.abc1a_A.201307282200-2300-2.gz
abcd1_abc_123456.abc1a_A.201307282200-2300-3.gz
abcd1_abc_123456.abc1a_A.201307282200-2300-4.gz
..etc..
abcd1_abc_123456.abc1a_A.201307282200-2300-10.gz
abcd1_abc_123456.abc1a_A.201307282200-2300-11.gz
abcd1_abc_123456.abc1a_A.201307282200-2300-12.gz
