I agree paper was a lot easier (but generally 4 section are easier) but saying that a score of 100 would be breached is far fetched. Actually the the point where 99.5 lies is more important because beyond this point you start having.
Lets analyse the paper section by section.
As a general rule as the number of section increases the cutoffs drop drastically. So I dont think people having more than 95% would have much difficulty crossing the cutoffs.
Section I
It was standard quant section for a 4 section paper. (refer to pre CAT-98 papers to understand what I am talking about). Though it had some easy but tricky questions(16,17,22,23). Lot of people who attemted those questions would know what i am talking about.
So anything from 18-25 is a good score depending upon time 25-35 mins given to the section.
Section II
Due to my verbal inability

I am not the right guy to comment on this section but I would do it anyway

After consulting junta after the mock I can conclude that this section was on the difficult side. But since it is the attempts/min is highest in this section people giving less than 30 mins would definately loose out (except for ppl like suzy

) Anything from 23-30 is a good score depending on the time 30-35 mins given to this section.
Section - III
This was the surprise packet of the day. This is the section which makes it this AIMCAT different from AIM505. It was comeletely straight forward atleast passage III,IV,V which lot of the junta attempted. SPM (score per min.) of .8-1 was attainable making it best scoring section. Anything from 19-27 depending on the time given 25-35 mins would be a good score.
Section IV
Standard DI section. Ideally nobody should have given more than 25 mins this section as it has only 35 questions. Anything from 15-20 should be good score given the time 20-25 mins
All in all a score of 70+ should give you a 99.5%
