So how about this? 
#!/usr/bin/perl
use strict;
use warnings;
use diagnostics;

if (@ARGV = 2){
my %delList;
my @orgList;
open (BEEPON, >>, "/path/to/beepon.file);
open (BEEPOFF, >>, /path/to/beepoff.file);
open (DELLIST, <, $ARGV[0]);
foreach (<DELLIST>){
   %delList{chomp($_)} = 1;
}
close DELLIST;

open (ORGLIST, <, $ARGV[1]);
   @orgList = <ORGLIST>
close (ORGLIST);

for (my $i = 0; $i < @orgList; $i++){
     if (exists $del{$orgList[$i]}){
         print BEEPON $orgList[$i];
     }
     else
         print BEEPOFF $orgList[$i];
     }
}
close BEEPON;
close BEEPOFF;

I can see how this would be more efficient. I'm not really sure that it is what you outlined... I'm still not entirely understanding the use of hashes. ie why are all the values set to 1?
