The "parent everything to a prop then scale" method is an old one that many people have used before.

The method you had scripted, even when corrected for various miscodings, produced undesirable results.
In cases like this, attention to the fine detail of what's needed can't be avoided (e.g. parent props like magnets are affected by their parents scale setting and so don't need doing seperately).

I've attached a working version of your original script so you can compare it and the one I ended up with (you can start a thread in the Python forum if you want to go into the details).
