Tag discounted orders

We're using Scripts to discount line items based on certain criteria using the  `change_line_price` method in the script. Is there some way in Flow to see if line item prices have been adjusted and tag the order as having discounts?


I tried a few triggers in flow like

If order  cartDiscountAmountSet  shopMoney  amount is greater than 0

but it isn't tagging the order. The notes on the order show that the Flow was run against the order. Should I be using a different value to check? Is this cartDiscountAmountSet value only set for discount codes?
