I have no direct experience with how the ActiveState folks package up 
their Python installers but my guess is that the Python 3.1 is launching 
in 64-bit mode and, at the moment, the only "standard" 64-bit non-X11 Tk 
is the one Apple supplies in 10.6 /System/Library.  The A/S version 
probably attempts to use it in 64-bit mode.  If you don't really need to 
run in 64-bit, try running it in 32-bit mode which may very well link 
with the A/S Tk 8.5.  I expect that either of these should work:

arch -i386 /usr/local/bin/python3.1

or 

arch -i386 /Library/Frameworks/Python.framework/Versions/3.1/bin/python3

You can tell which Tk is being linked to for the 32- and 64-bit version 
with:

otool -L $(arch -i386 python3 -c 'import _tkinter;\
               print(_tkinter.__file__)')
otool -L $(arch -x86_64 python3 -c 'import _tkinter;\
               print(_tkinter.__file__)')
