I would say the situation for Scons is slightly different than the one for Mercurial:
  - In order to use Scons you have to have a python installation of your own - Mercurial installs its own one.
  - Using Scons means you have to write your build script (SConstruct) in that version of the Python language, that is also used by Scons.

I am currently working on a project, where Python is used for several things and the team decided to go for Python 3.3. So in order to need just a single Python installation for being able to contribute to this project, i took the branch https://bitbucket.org/userzimmermann/scons, built a scons-local package from that and integrated that into our repository. That works quite well with PYthon 3.3, although we sometime experience problem when doing parallel builds (e.g -j4) - Scons is trying to access a build target while a custom builder still has a handle open for that file. But since we are using a 'hacked' version of Scons, i will surely not complain.

So i guess from my situation you can see, that it would be much to my regret if support for Python 3 in Scons would be considered subordinate. On the contrary: I find Python 2 old-fashioned and i am waiting for Scons' Python 3 support wishfully.
