 From what I understand (which may be incorrect!), this is not client side - 
It's an attribute on each file under SVN control. The standard from-source 
tarball build defaults to honoring this expansion.

That would only get you the revision of the last change of that one file, 
hence the issue. There is no global revision number accessible from a $tag$.
