Teachers don't submit SAC rankings: they submit the score received by each student for each AOS (which may be one SAC, or a composite of multiple). They're not supposed to alter them at all, except through cross-marking (so, maintaining consistency and fairness and not just making wilful, arbitrary changes).
I don't know what info you get on your statement of marks, but if it's the post-moderation SAC scores, especially a letter grade and not a number, that won't really help you.
I would always try to deal with things on a local level first, and see how it goes before escalating. Maybe go to your academic coordinator or some equivalent and say that you were hoping to see the marks that were submitted to VCAA for you for each AOS. They must just tell you and then you'll get peace of mind either way.
