You might want to have your shipping table (shipping.asc or whatever)
utilize a usertag/subroutine to calculate shipping (it could also do the
tiered pricing you mention above instead of doing that via separate
shipping.asc entries).

In that same routine, you could handle/omit gift certificates.  I
assume there is something about your gift certificates that identify
them as such.

You can loop through the items in the cart with:

     for my $item (@$Items) {
         Add to shipping_total unless gift certificate
         Cart data in this loop is accessible as $item->{quantity}
     }

Use the [dump] tag if you are not familiar with the @Items structure
and contents.
