IMO it would be better for emacs to just run

py.exe script.py

and py.exe can read the shebang and do the right thing. This saves the emacs code
from having to duplicate the shebang line processing logic that py.exe uses
(which, as we know, is unusual. So for a cross-platform you can have a shebang
line of #!/usr/bin/python3.2, and on Windows it will still call the appropriate
Python 3.2 even if it's not in /usr/bin, as there's no /usr/bin :-))
