Is my NATA score of 112 along with 92% in 12 boards enough to get me into a good architecture college?

NATA marks of 112 are not good enough to get you entry to top ranked colleges and so you’ll have to go to lower ranked colleges. However, there are a few new and emerging colleges that are much better then B grade colleges but being new are ranked lower. You should apply there. I suggest you look up WSPA, a part of World University of Design, Sonipat. They have however only 40 seats, so you’ll need to hurry up and see if they are still open
