Are all Xperia Play Optimized games compatible with the Xperia Z/ZL's native DualShock 3 support?
User poo-tang provided an answer in the xda forums:


  Xperia Play games don't work this way so won't be interchangeable. These new games are HID (Native Android built in virtual controller/mouse) supported (only available on Android 3.1 and up) Xperia Play uses Sony framework only. The games are coded for one or another (sometimes both if developer has added support for both)
