Something along these lines maybe, since the check is always identical ... 
sub compare {
  my ($points, $quota) = @_;
  my @comparisons = (
    # points, quota
    [ 18000, 24 ],
    [ 16000, 23 ],
    [ 14000, 22 ],
   ...
  );
  foreach my $cmp ( @comparisons ){
    return $cmp->[1] if $points > $cmp->[0] && $quota < $cmp->[1];
  }
  return 15;
}

Ah, now i see that there's a pattern... youre compare2 is close.. i think if you make it $points -= 2000; it will work.

Update: since patterned, can generate @comparisons like this: 
my @comparisons = reverse map { [ ($_-15)*2000, $_ ] } 16 .. 24;

Update: fixed typo of $cmp[0] needing to be $cmp->[0]
Update: thanks to ihb for pointing out the need for the reverse of 16 .. 24 instead of just 24 .. 16 which is an empty list.
