I actually got the right answer, but only because I misread the question--I assumed it was something to do with string sorting (where the sort order would become 1, 10, 11, 2 rather than 1, 2, 3, 4) and picked the nearest answer to what I thought would happen. Didn't even notice that the string value entered in the second value line was different from the integer for that line!

That being the case, I wonder why the question setter didn't just use a pair of integers? Having the apparently completely irrelevant string conversion in there just confused the issue, IMHO.
