Setting the creator would solve it for a single file, but I want to 
solve it system-wide (so all .py files that don't have an explicit 
creator are launched with (at the users' option) PythonLauncher or 
PythonIDE.

Bah. And is there a way to send an AppleScript command to the finder 
(or maybe something else? A preference panel? A shell interface?) to 
accomplish this?

Adobe Acrobat Reader does seem to have a way to do this. At least: when 
you fire up a new Acrobat Reader for the first time it tells you it 
isn't the default app for pdf files, and whether you want to change 
that. Would they be using the private LS API, or would they have found 
some other way of doing this?
