Hi Rockstar20,
First off, a 720/Q49 is an outstanding Score, so you can comfortably apply to any Business Schools that interest you. Many Business Schools have publicly stated that they do not use an applicant's IR score when evaluating an application, so you likely have nothing to be concerned about with an IR4. However, if you're interested in what a specific School/Program thinks about the IR score, then you should research that School directly (you might also consider contacting the School to ask). By extension, if you're interested in any highly-competitive Schools, you would likely find it beneficial to speak with an Admissions Expert about your overall profile and plans. Those Experts should be able to answer your Admissions questions and help define the specific areas of your profile that could use some improvement. There's a Forum full of those Experts here:
