Ravi,
I am no expert and scored much lesser than you did. But I think, besides your score, there could be some other parameters to be taken into consideration.
1) Did you solve all the questions and then got 1?
2) How much time did you consume in this section.
3) Why didn't you mention your AWA score and how much time it took to compile the essay?
Surprisingly 'Time taken to finish a section' is overlooked by everyone. Nobody ever talked about it but I think it is also taken into account by the ad-coms to assess your candidature. There is a great difference between a person who solves a problem in 1 minute and a person who takes one month to solve.
I do not know if IR is relevant at this moment but it could be a deciding factor in-case of a tie between two applicants.
