You don't want to install 3.0 but the newest release of Python 3 which
would be Python 3.1.1, or is there another reason why you need exactly
3.0?

Sure. You can compile them yourself. Python 2.6 and 3.1.1 will install
itself into /usr/local and will therefore not interfere with any Debian
packaged Python release.
You should make sure to delete /usr/local/bin/python though so that '#!
/usr/bin/env python' will still resolve to /usr/bin/python . This is
necessary because there might be some programs packaged by Debian that
do not declare the Python version they need to run with explicitly if
they won't run under another version as the one currently shipped in the
Debian release. (2.5.4)
The situation in regard to '#!/usr/bin/python" vs "#!/usr/bin/env
python" is not yet resolved in Debian and there might be a couple of
packages in Debian that install scripts with the "#!/usr/bin/env python"
shebang even if they won't work with 2.6. These packages should have
"#!/usr/bin/env python2.5" or "#!/usr/bin/python2.5".
I would prefer all programs installed via the package manager to use
"#!/usr/bin/env python[X.Y]" instead of "#!/usr/bin/python[X.Y]" because
that would mean that I could use them regardless of the Python version
"env python" resolves to in the currently configured environment.
If you feel the same write a mail to the debian-python list and tell
them about *your* needs.
kind regards
