Try this for cat to cat discounts:

function get_discount($discount_item, &$all_items) {
        $discount = 0; 
        for ($dis=0, $n=count($this->discountlist); $dis<$n; $dis++) {
           $found_match = false; 
           $li = $this->discountlist[$dis]; 
           // Based on type, check ident1
           if ( ($li->flavor == PROD_TO_PROD) || 
                ($li->flavor == PROD_TO_CAT) ) {
              if ($li->ident1 == $discount_item['id']) {
                 continue;
              } else {
                $found_match = true;
              }
           } else { // CAT_TO_CAT, CAT_TO_PROD
           // check to make sure a discount product has been added
              if (zen_product_in_category((int)$discount_item['id'], $li->ident1)) { // modified to support linked products and top level categories 
                 $found_match = true;
              } else {
                continue;
              }
           }
           if ($found_match) {
             for ($i=sizeof($all_items) - 1; $i>= 0; $i--) {
                 if ($all_items[$i]['quantity'] == 0) 
                    continue;
                 $match = 0; 
                 if ( ($li->flavor == PROD_TO_PROD) || 
                      ($li->flavor == CAT_TO_PROD) ) {
                    if ($all_items[$i]['id'] == $li->ident2) {
                       $match = 1;
                    }
                 } else { // CAT_TO_CAT, PROD_TO_CAT
                    // check that a product in the other category exists
                    if (zen_product_in_category((int)$all_items[$i]['id'], $li->ident2)) { // modified to support linked products and top level categories
                       $match = 1;
                    }
                 }

                 if ($match == 1) { 
                     $all_items[$i]['quantity'] -= 1;
                     if ($li->type == "$") {
                        $discount = $li->amt;
                     } else { // %
                        $discount = $all_items[$i]['final_price'] *  
                                    $li->amt / 100;
                     }
                     return $discount;
                 }
             }
           }
        }

        return 0;
    } 

You'll have to apply this to the other methods, but it's all I needed.
