This I think is perpetuating the metaphorical myth,

A pack of cards in of itself has an entropy whether sorted or random.

A system of a pack of cards and a shuffler or sorter also have an entropy. The sorter can do work and sort the cards and the system's entropy will increase. Or the shuffler can do work and shuffle the cards and the system's entropy will increase. We could argue, possibly quite accurately, that it takes more work to sort. But then the shuffler can continue shuffling until the same amount of work was done.

In what way will the entropy of the cards be lower for the sorted pack?
