So you're set: 2.6.1 is more recent than 2.6...
But you probably shouldn't use a dmg: install Scipy from sources, it's far easier to help you.
Assuming you have xcode installed, and a proper gfortran (I think this one is the recommended one: http://r.research.att.com/tools/)

* Install numpy first. make a local install by using the --user flag when calling python setup.py install. No need to install an additional Python if you use --user, you won't be messing with your system

* Then, install scipy, using the --user flag as well. Don't bother for UMFPACK for the moment

* You may want to set CFLAGS="-arch x86_64" before installing numpy and scipy.

* Let me know where your problems are (off-list for now to reduce the noise), post the log of your build somewhere.

Don't worry, it's straightforward, provided you stick to the Python that comes w/ SnowLeopard
Good luck
