Are you looking to discount if there are 20 or more line items more than 
20 total pieces regardless of the number of line items because your 
example above is looking at neither, it is testing to discount if the 
line item has 20 or more pieces regardless of the rest of the order.

If you want 20 or more 'line items' you can use this usertag:

UserTag line_items     Routine <<EOF
sub {
        return @{$Vend::Items};
}
EOF

and if an [if] on line_items

or if you want to discount based on a total of 20 pieces for the entire 
order, you might try this (haven't tested it)

UserTag total_line_items AddAttr
UserTag total_line_items Routine <<EOF4
sub {
  my ($opt) = @_;
  my $output;
 
  my $cart = $Vend::Items;
  my $item;
  my $ttl = 0;
  foreach $item (@$cart) {
    $ttl .= $item->{quantity};
  }
  return $ttl;
}
EOF4
