What level of autisim could you predict my son to be?

I just want to have ideas on what level he might be. This past friday he went to a autisim evaluation. They did varies of things. He suprised me on some things. He can speak words, label objects,and understand what your saying. But, the thing with that is he cant say things like put the toy in my hand. They doctors were shocked about that. He scored high on things. My son is 3 1/2 yrs old. They did these regular blocks and had him imitate what the doctor had did and he cold do it. But, when it came to these sponge blocks, where it had one side yellow and the other side black. The picture showed 3 black squares on top, while 3 yellow squares on the bottom. The doctor did it herself and than told my son to do it. When he dit it, he flipped all the square things to the black side and lined them in a straight row and his eyes were goin back and forth with the line. He completely ignored the doctor than of what she was doing. He is very detailistic. He does self stimulating wiggling his toes back and forth and his fingers also at the same time. But he didnt do it there. Than they try to have him on up and showed him how to do it. But he couldnt. Also, the doctor showed him how to put a string in the paper hole twice. He would do the first hole but he would keep pulling. I told them they should see him with his cars. So, they got his cars out. He's lining them up like he always does. Than the doctors kept messing with his carsdestroying the line. My son got mad like stop it and started bangin the doctors hand with the toy car. It was funny tho. Than before we left I asked the 1 out 5 doctors there, So do you think he has autisim??? She ad yes but Mild Mild Mild autisim. Okay, so what does this mean? aspergers??? or what?? I have a IEP meeting Dec. 5th. Than my son didnt want to go and started throwing a fit. so, yupp that clears up everything. O yea, when he stares at his cars wheels while got it lined up thats when he gets excited and does his finger and toe thing. But, no one can be payin attention to him. So, can you guys please give me an idea thanks!
