River,
I don't know much about test scores, but a friend has a son with dyslexia and she relates the following stories about him, maybe these would help you understand what Mia was asking about.
He can't put his underwear on the right way, no matter how many times they tell him the right way. He can't figure out the before and after, yesterday and tomorrow sequences. (He says yesterday for tomorrow and vice versa all the time.) He also can't find his way home from local stores, he always go in exactly the opposite direction.
Maybe if you posted some questions in the 2E thread you'd get more responses. I'm sorry you aren't getting any help so far. Please don't give up yet. Many people on this board are concentrating on children more than adults, since they are looking for help for their kids, but I'm sure some will find you soon.
