You could enable the api log and see what TWS is sending over the socket.
I haven't looked at the latest api but earlier versions did not inform TWS of the language used to implement the client api. In other words TWS does not know whether a client is python or Java or C++.
If the data is correct in the api log but incorrect in python then that is useful. If the data is wrong in the api log it would be wrong in all languages.

I also should have added to the original post that the auction imbalance displays correctly in the TWS GUI, which suggests fairly strongly that the problem is occurring somewhere in the API.
