Your specifications are unclear, and your code needs much better structure.

Here is my interpretation, with code to help get you started (untested): 

 
use strict;
use warnings;

my $lastrecord = $rdb->last_record; # Call this only once

my $i = 0; # Starting record number ?
my $counter = 0;

while (my ($recordnumber, $X, $Y, $comments) = 
                 $rdb->get_record($i,"X", "Y");
   $i = $recordnumber;
   last if $i > $lastrecord;
   
   if ($X < 20){
      $wdb->set_record($i,$X,$Y,"Good");
   }elsif ($Y > 5){
      if (++$counter > 10){
           $wdb->set_record($i,$X,$Y,"Worse");
      }else{
            $wdb->set_record($i,$X,$Y,"bad");
      }
   }
}

When do you reset $counter ?

     Theory is when you know something, but it doesn't work.
    Practice is when something works, but you don't know why it works.
    Programmers combine Theory and Practice: Nothing works and they don't know why.         -Anonymous
