The number of possible sorting orders is certainly very high, but given that many new decks start out in the same order then the chances that the first one or two shuffles could have the same result (given the same shuffling operation) seems quite high.

I'd bet a buck or two that there are one or two close up magicians that could do it within a reasonable number of tries.
