I love that site! It was definitely really helpful for me in finding out whether some of the schools seemed to a be a good fit for me.
Great to see a fellow HR/ILR applicant! It sounds like you have some great work experience, it would definitely be cool if we ended up at the same school! Minnesota is definitely one of my top choices of the schools on my list, particularly because of the strength that you mentioned. As for the statistics regarding graduates and careers, I wasn't aware that the statistics regarding jobs are higher for Minnesota than Cornell. Given that Minnesota's program is housed in Carlson, I'm not surprised that it does a good job of placing graduates. In terms of geographical diversity for job placements, however, it seems Cornell does a better job of placing it's grads throughout the US and abroad whereas a large percentage of Minnesota's grads stay in the midwest (56%), which isn't necessarily a bad thing. Cornell grads seem to have a higher mean salary ($73,982 vs. $71,284 for 2010) and higher signing bonuses ($12,065 vs. $10,335). Both seem to be great programs, I wish you the best of luck in your applications!
The TC Masters in Organizational Psychology seems much less focused on human resources (or industrial relations) from what I have been able to gather, but it seems to do a good job of placing its grads in hr careers. The program, however, strongly recommends that you have significant full-time work experience if you want to apply to the program. They actually recommend that you defer applying to the program until you've spent some time in the workforce.
They have an extremely helpful FAQ PDF file that answers a lot of basic questions about the program: http://www.tc.columbia.edu/i/a/document/12477_MAFrequentlyAskedQuestionsOrgPsych.pdf
