Your idea of sorting first and then comparing is exactly right. There may be a cleverer way, but I don't know what it might be.

Your "serialization" hack is probably not satisfactory. You will need iterative sort and comparison for this to work for arbitrary nested arrays. Recursion is an attractive way of writing that for not-too-deep nesting.
