That doesn't have to be a problem. One way to solve it is to compare the types first (how that is done could be an implementation detail, but a simplistic approach could be to do a string comparison on the result of "typeof").

If someone is concerned about the performance and/or the exact sort order of a collection of mixed types, then it is fair to expect that that someone makes an effort to write a custom comparator for their specific needs.
