Some people called Apple regarding this and it seems if you bought MS2 within 30 days before today, you can get a refund. You bought it outside of this window, so the answer will probably be "no".

Just to let everyone know, I reached out to Apple through the online process and Apple resolved this!!! I should get a refund in 7 to 10 days. This will allow me to purchase MainStage 3.

Apple Customer Service was a pleasure to work with and I won't hesitate to engage again if needed.
Apple also supplied me with the following:

Thanks Blueberry for the point in the right direction. :-)
