What I do is have the action for the form in OneZPT point to AnotherZPT. Then from AnotherZPT you can call SomePythonScript which will call the ZSQL method and do any data manipulation necessary, and then return the data to AnotherZPT. This works nicely because you get the benefit of having access to the REQUEST variables in both AnotherZPT and SomePythonScript without having to pass it around. 

I think that you could use the same technique to return the result to OneZPT instead of AnotherZPT if that is what you really want to do. You could have the form action point to OneZPT and give the submit button of OneZPT a distinct name like hasbeensubmitted or something. Then set up a tal:condition to test for hasbeensubmitted. If it is there, call SomePythonScript to process the ZSQL and return the results to OneZPT and go on from there.

Hope that helps,
Chris
