So if that is the case, then it seems you may need to play around with the weights that can be assigned to answers in the extended properties for the question object.

It seems that your quizzes are pretty complex in how they score, but ToolBook does permit complexity. It may take some trial and error using a one page book (to save time in getting it right). Once you get ToolBook's system to correlate with your own, then the score in ToolBook should match the expected result and Moodle will get the correct value.
Most developer's just use a score setup like shown above. But you can make each answer to a question have it's own weight if you want.
