Magento - get price rules from order

Question

does anyone know how one can get the catalog- and cart price rules from an order?

I know that I can get the discount percentage from an order item via the method

Answer 1

What might help you though:

$order = Mage::getModel('sales/order')->load(20569);
echo Mage::helper('sales')->__('Discount (%s)', $order->getDiscountDescription());

This prints out all the discount rules name which have been applied to the order.
