Hi Pritesh,
As I mentioned before, I don't know how any specific School will view your IR score (but it's likely that the Schools will NOT care about your IR score). If you pose this question in the Admissions Forum (on this site), then you might get a more direct answer.
Have you checked the Official websites for any of these Schools? Schools usually provide relevant information about incoming class 'profiles', average GMAT scores, etc., so you might find an answer that way. If the Business School Admissions Officers have done any interviews or press releases, there might even be information about how the School factors the IR score into the review process (so try 'googling' what you're looking for).
GMAT assassins aren't born, they're made,
