LLVM releases are time driven (every six months, roughly) while Apple's "LLVM Compiler" is feature driven, so there's no actual requirement for the two version numbers to be connected... however much we may want them to be, even if only remotely for clarity's sake! (but thanks for that "based on LLVM 2.9svn" explanation!).
Another most-probably-far-from-correct assumption is that Apple keeps its LLVM additions/modifications/what-not/whatever in the same public repo as stock LLVM sources, so I'd say it is perfectly conceivable that those tags that spawn the Xcode "LLVM Compiler" releases and that the OP is seeing in clang --version are kept private in an Apple server somewhere inside the Mothership.
