Your issue is not entirely clear to me -- can you clearly state what your expected output is? It seems like it's operating reasonably to me.

As a side note, you iterate over your hash values in checkControlMap. To quote our illustrious figurehead,

Doing linear scans over an associative array is like trying to club someone to death with a loaded Uzi.
-- TimToady
That could be written as 

sub checkControlMap
{
   my $check = $_[0];
   print "Look for control [$check] - ";
   my $process = $process_control{$check};
   if (not defined $process) {
       print "WARNING [$check] was not found. - ";
       $process = 1;
   }

   return $process;
}

with no change to functional behavior.

Update: Actually, it does cause a change in functional behavior, as mortiz points out below. So use this.
