Treat them as two draws from possibly different, independent distributions.

The question is whether the distribution that drew 7 “stochastically dominates” the distribution that drew 5. You may or may not be able to conclude that based on the available data and assumptions about the distributions.

For example, if you assume that the two distributions are approximately normal with very small variances, then you can probably conclude that the distribution that drew 7 stochastically dominates the distribution that drew 5. But if you assume that the variances are large, then you probably can’t conclude that.
