Table Rate Price/Quantity Discount Metadata Name Change

Hi all. Before the recent update, I was using a custom function to display the table rate prices on the single product page. Now this has been changed to “Quantity Discounts” so I believe the metadata name value has changed. All of my old products (3000 of them) have the old post metadata name.

Is there a way to update this to the NEW name?

Here’s the old function I’m using:

function add_in_table_rate($product_id){
	$output = '';
	$metadata = get_post_meta( $product_id , '_wpsc_product_metadata', true);
	if(!empty($metadata['table_rate_price']['state']) &&
		$metadata['table_rate_price']['state'] ){
		echo '<h3>Discounts available on multiple quantities!</h3>';
		$output = '';
		for($i=0; $i < count($metadata['table_rate_price']['quantity']); $i++){
			$output .= "".$metadata['table_rate_price']['quantity'][$i]." for
			".wpsc_currency_display($metadata['table_rate_price']['table_price'][$i])." per item <br />";
		}
		$output .= '<br />';
	}
echo $output;
}
add_action('wpsc_product_addon_after_descr','add_in_table_rate');

Any help you can provide would be greatly appreciated because any new products I add or old products I modify get updated using the new value name.

Or if anyone has a better way of show the prices of the Quantity Discount I’m also open for other suggestions.
