First, I'll suggest adding "use strict;" and "use warnings;" at the top of your script. You use $tottopCount in your calculations, but I don't see it getting set.

As far as how to handle your problem, just to give you a start, I'd suggest doing one thing at a time, add as many LOWn to as many MIDn as you need. Something like: 

while( keys %addedLow < keys %lowlevelH ){
  for my $lowLevel ( keys %lowlevelH ){
    if( exists $addedLow{$lowLevel} ){
      next;
    }
    if( $mid{$midItem}{CNT} + $lowlevelH{$lowLevel} <= 35000 ){
      push( @{$mid{$midItem}{LowLevel}}, $lowLevel );
      $mid{$midItem}{CNT} += $lowlevelH{$lowLevel};
      $addedLow{$lowLevel} = 1;
    }
  }
  $midItem++;
}

Then repeat the process for adding mid to top.

Note that this is not tested and is incomplete, just intended to provide some thoughts about a possible direction to take.
