Yes, the Battles subscription discount should apply to older sets as well as Pathfinder Battles singles.
It should automatically apply when items are in the shopping cart. However, we have been having some bugs with the discounts not applying correctly (this should be fixed in the near future, I'm just not sure exactly when).
If it's not working for you, let us know. We can either apply the discount after the order is submitted, or apply it an then submit it for you from our side.
If you have any further questions or concerns, please let us know.
Thanks!
