Hi SilverBull,
A 760/Q49 is an outstanding score; you have a GMAT score that will make every Business School happy regardless of any IR score that you might have. Many Business Schools have publicly stated that they do not factor in an applicant's IR scoring during the evaluation process, so you have nothing to worry about there.
The Schools that you listed are all VERY competitive though, so you have to think about how your OVERALL application comes across. As such, you might consider working with an Admissions Expert on your applications. While no Expert can guarantee you anything, they can help you to make sure that you're presenting all of your accomplishments and ideas in the proper ways.
You can pose questions to those same Experts in this Sub-Forum:
