I would avoid writing such elaborate sorting subs and use DBD::RAM. This is the first timer for me, BTW.

This is yet untested tested now: 

use DBI;
use SuperSplit;
 
my $data;
{
  local $/ = undef;
  $data = <DATA>;
}
$data=~tr/\-/,/;
 
my $dbh = DBI->connect('DBI:RAM:','usr','pwd',{RaiseError=>1});
  $dbh->func({ table_name  => 'file',
      col_names   => 'source,year,month,time,sip,sport,dip,dport,hits,
+acl,mlnum',
      data_type   => 'CSV',
      data_source => $data,
      }, 'import' );
my $ar =  $dbh->selectall_arrayref(qq[SELECT * FROM file ORDER by  spo
+rt asc,  time desc ]);
 
print superjoin(',',"\n", $ar );

Of course you will have to write your own sorts here, but that is fairly easy now, just adjust the SQL ORDER string.
