Quick comment : You should add the "= %{version}-%{release}" to the "Provides:" in your document.
Otherwise, Tcl seems completely broken when it comes to multilib... [1] and you seem to be aware of the major issues as the TODO section shows. But it contains tasks so critical that I wouldn't bother trying to push these packaging rules forward until they are taken care of. For instance, replacing the "/usr/lib/tcl8.4 -> /usr/share/tcl8.4" symlink with a real directory is... errr... pretty much impossible for rpm to do. You might be able to hack around it, but it'll be ugly.
Good luck! :-) Matthias
