You should have a Python Launcher application in the MacPython 2.6  
folder in Applications. When you double-click on a script this is  
what should get launched. If not, then you have to do a Get Info on a  
Python script; .py, .pyw, .pyc have to be done separately. I'm  
guessing the MacPython installer sets IDLE as the default application  
for scripts.

If you double-click the Python Launcher application you can verify  
which Python it is going to use to open a given script. In my case, / 
usr/local/bin/python is used. It could be that in your case it is  
still set to /usr/bin/python or the location of an older default python.

Here's some background that may help. I'm using 2.5.4, so the output  
below shows what you would see on your machine for various links.  
Below that is my info about ~/.MacOSX/environment.plist, the old  
magic file for scripts launched from the Finder.

Unfortunately, I haven't looked at whether you still need the  
environment.plist stuff or not. It used to be that in order for  
launches from the Finder to be able to find the appropriate  
libraries, you needed one. It might still be relevant for me because  
I have my "working copy" of PythonCard and some other libraries set  
to be found by the PYTHONPATH defined in environment.plist.
