I concur with
Engr2012 's thoughts. If M7 is what you are aiming for, I'd highly recommend retaking the exam.
Don't you think retaking the exam just for the integrated reasoning would waste time I could otherwise use to write good essays? I am trying to understand how certain one can be the IR can raise a red flag when no stats are published.
Fair point, but to be absolutely blunt here, you are wasting your time asking this question here when no one here is remotely qualified to tell you with absolute certainty that IR wont matter for M7 application. Not even I, who is already studying at an M7 will be able to tell you that low IR score will not raise a flag, unfortunately. You can take that risk and it will be your call at the end of the day. Keats and I just mentioned what we personally think about the application process. Per the stats, the acceptance rates to M7 hover between 9%-20% and with this low percentage, its entirely your call to take that chance. People with low GMAT or GPA usually use the optional essays to tackle the low score issue head on without giving another GMAT or trying to create an alternative transcript.
TL;DR: Take a call, either give GMAT to improve your IR score when GMAT is still fresh in your mind or let it go but do answer this question proactively in your optional essays. Either strategy has been shown to be effective in the last few years. If you think rest of your application will plug in all the 'gaps' with your low IR score, then, yes, dont waste your time on another GMAT.
Hope this helps.
