well, this was interesting, I didn't know about arch. As you supposed, running python3 produces a Python process that Activity Monitor says is "Intel (64 bit)".
However, arch -i386 python3 produces exactly the same thing as I get using arch -x86_64, namely, an Intel(64 bit) process (and loading the same _tkinter.so). Hmmm. This would suggest there is only the one architecture defined in its binary? applying otool -L to the _tkinter.so that python3 is loading reports "/System/Library/Frameworks/Tcl.framework/Versions/8.5/Tcl" and etc, so indeed, the Apple Tcl is baked into the dynamic load lib distributed with Python3. I cannot find any other version of _tkinter.so that might have been installed by ActiveTcl. So I'm pretty baffled, as well as disappointed that there's been no response in the ActiveState "support" forum. However, thanks for your help!
