Yup, I'm afraid so. The responsibility for Adobe/Apple font liaison is just now transitioning away from me to Christopher Slye, but I made a nice list of outstanding issues for him and our test team to follow up on, and this is on it.
As I've written elsewhere, the whole notion that we have to identify a "primary" script or codepage for a font is kind of broken in today's world of multi-script fonts. Apple's attempts to do it sometimes mess up, and so do Adobe's. (Some of our applications have similar problems, even outside of OS X.) We hope to revisit the whole issue in the future.
