3.1.2 and 3.1.3 should be identical in that respect.  The most recent 
3.1.2 installers with 32-bit/64-bit support that I built (around 
3.1.2rc1 time) had them:

As I noted earlier, 32-bit/64-bit 3.1 (and 2.6, for that matter) builds 
do not support architecture selection via the arch command on 10.6, 
which will always prefer to launch 64-bit if possible.  A feature was 
added to 2.7 and 3.2 to support this.  For 2.6 and 3.1 systems, the 
standard ./configure options --with-universal-archs="3-way", "intel" or 
"all" create the separate 32- and -64-bit executables.  Running on 10.6 
you can see the problem with the ActivePython 3.1.2.4 - it always runs 
in 64-bit mode:

$ python3.1
ActivePython 3.1.2.4 (ActiveState Software Inc.) based on
Python 3.1.2 (r312:79147, Oct 22 2010, 10:36:09) 
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
Module readline not available.
>>> import sys
>>> sys.maxsize
9223372036854775807
>>> ^D
$ arch -i386 python3.1 -c 'import sys;print(sys.maxsize)'
9223372036854775807
$ arch -x86_64 python3.1 -c 'import sys;print(sys.maxsize)'
9223372036854775807

(Also, I don't have a 10.5 Intel system handy at the moment but I wonder 
how the ActivePython Tkinter would work at all there since there is no 
/System/Library/Frameworks/Tk.framework/Versions/8.5/Tcl or Tk).
