I read it in from a file as a command line

Answer 1

The easiest thing to do is to parse the pairs into lists and then just sort them:

lin = [i.strip().split(', ') for i in open(sys.argv[1]).readlines()]
lin = sorted(lin)

In case you want to sort numerically, just cast to numbers:

lin = [map(int, i.strip().split(', ')) for i in open(sys.argv[1]).readlines()]
lin = sorted(lin)
