I have not tried it myself. I went as far as downloading the tickets on my iPhone and storing in my passbook. You would log in through your MyCuse account to DL to your phone. Then you bring the passes up on your screen and have it scanned like a regular ticket. For multiple tickets, you would just need to swipe between passes and have all QR codes scanned.
I have no idea if the process works that smoothly in practice, like I said, never made it to the gate with them. Ended up not going to midnight madness and instead emailed the tickets to someone else, so it cancelled the codes I had.
