Discounts for subscriptions

Hi, I am applying a discount for purchases over 3 units and I also have the possibility to subscribe to my products. I would like the discount to be applied to renewal orders as well as long as they meet that condition, but it is not happening. The subscriptions plugin generates a new order every time, for example if a customer is subscribed to receive 3 units every 3 months, a new order is created in the admin automatically, but it is not taking the discount. Would it be possible to fix this? The page I need help with: [ log in to see the link]
