Thanks for the reply, I am using the 32-bit version. I did make some progress yesterday when I noticed that the iLok I'm using became "detached" within Windows for some reason. A reboot solved that problem and I got all the instrument channels except midi drums to work. So yes, EastWest's Play does indeed work in BB 2012 except for the drum channel as of now. A small inconvenience as I just copy the midi drum track back into Sonar where it will end up anyway.
