Hi possible894,
Thanks for sharing your profile information. Although you can point to instances where you were doing non-IT work in your job, the "Male Indian IT" profile can be hard to shake, and thus I think there is still a risk you will pooled with others who fit under that profile.
While your GMAT is still in the 20-80 range for those schools, it is on the low side, especially for Wharton/Chicago/Columbia. Tepper is probably a bit more in range; I'd recommend selecting 1-2 from that top list, and adding another school of a similar nature to Tepper.
Best of luck,
Daniel Richards
