I chatted with Stephan Lavavej a few minutes ago, and he's confirmed this is fixed in MSVC 2013. He specifically referred me to his blog:

specifically this:

[from blog]
Scoped enums were implemented in the Visual C++ 2012 compiler, but due to a long story involving a compiler bug with /clr, we weren't able to use them in the STL for that release.  In Visual C++ 2013, we were able to get rid of our fake scoped enums (simulated by wrapping traditional unscoped enums in namespaces, which is observably imperfect).
