Sorting a single value is not particularly useful (I can't think of any alternate orderings aside from the one value first (or last if you're a pessimist)). Sorting a list of values is far more useful...arrays certainly also help but you could also keep things outside of arrays and purely in list context though it would likely involve a lot more typing and/or control structures.
