Just as a counterpoint to this  People don't normally put 0s before a number. I would expect a lot of people would think "007" is "00 and 7" not "7" and that leading zeros are "not part of the number." I know an informal study of "all of my friends online right now" (none of whom are computers scientists and many of whom are artists or fairly nontechnical people) as told me that they expect that "04" would come before "2" because of the zero. It was presented this way "if you had a list 2, 3, 4, 5, and you were to add 04 to it, where would you put it?" so I don't think my question was presented in a leading way. The problem is, now you're arguing "mathematical rules." We've already established people don't think in mathematical rules. I doubt people see "04" and think "four". They think "ohfour." The zero is not an insignificant and ignored digit in the way people speak, read, or think the number. Except in math. But we're talking "normal people" here. Instead of us trying to think about them, if we're going to base this on "normal people" let's do a poll. At least this way we're not extrapolating our opinion on them based on *mathematics*, something few people think in.
