After fixing the postinst, I got the following output but the package configuration succeeded (dpkg lists it as installed):

python3.1 needs updating to. Working on them both.

python3.1 and python3-defaults are both uploaded. Build queues are huge today, so it will likely be a while before the packages are built. The python3-defaults update fixes the shebang issue and correctly depends on the newer python3.1, so you won't be able to install the new python3 package without the new python3.1.
