So.... we do not have have a good reference yet about the integration reasoning section. In the last 2 years (since 2012) schools have generally ignored it. Very low scores like yours have potentially raised questions but high GPA's and high Quant scores usually off-set it.
However, I expect it to change in about 6-18 month time frame.
1. The first candidates who took the IR section have graduated and GMAC will do a nice little regression to show schools how relevant it is
2. It usually takes them a few months to do the study of GPA/employability/etc and then analyze another 3 months, and then they will issue their research - Dec 2014 is my guess.
I think you should retake since:
1. 3rd percentile is really bad. 50th would be passable but 3rd is terrible
2. it will take you one week to raise your score from 3rd to 67th percentile.
3. It will matter more for your class
4. You may score more on the GMAT in general (if you keep current and fresh), and that may help your case/profile though it is quite strong from what I see.
5. Your quant score is not fabulous - you can do better as a Finance/Logistics person. This shows that you did not take the test very seriously (sloppy IR score, and sloppy for your field quant score) - Schools want people putting out max effort.
Hope this helps.
