Update stock value

I wrote some dirty (advices/fixes are welcome) code to update stock value. Can you include it into next release?

bee_colony.products.inc

 * Update stock value.
 *
 * @param $batch
 *   Array of associative arrays with stock data:
 *       - sku:          Must be a string. Its mandatory to have this key in the array.
 *       - active: Must be a boolean. Default is 0.
 *       - stock:  Must be an integer. Default is 0.
 *       - treshhold:  Must be an integer. Default is 0.
 *
 * @return boolean
 *   TRUE if no errors.

function xmls_bee_colony_stock_update($batch) {
        foreach ($batch as $item) {
                if (!isset($item['sku']) || trim($item['sku'])==='')
                        return services_error(t("SKU must be provided."));
                $result = db_query("SELECT nid FROM {uc_product_stock} WHERE sku = '%s'", $item['sku']);
                if (db_result($result)) {
                        db_query("UPDATE {uc_product_stock} SET active = %d, stock = %d, threshold = %d WHERE sku = '%s'",
                                $item['active'] ? 1 : 0, intval($item['stock']), intval($item['threshold']), $item['sku']);
                } else {
                        $result = db_query("SELECT nid FROM {uc_products} WHERE model = '%s'", $item['sku']);
                        $item['nid'] = db_result($result);
                        if (!$item['nid'])
                                return services_error(t("Product with SKU=" . $item['sku'] . " does not exist."));
                        db_query("INSERT INTO {uc_product_stock} (sku, nid, active, stock, threshold) VALUES ('%s', %d, %d, %d, %d)",
                $item['sku'], $item['nid'], $item['active'] ? 1 : 0, intval($item['stock']), intval($item['threshold']));
                }
        }
        return TRUE;
}
