I think that a "rigged deck" assume someone knowingly did something. In this case, from the story, this was an accident and not intentional.
Of course even if the deck was rigged (say someone at the manufacturer turned off the shuffle process) while it would be defacto rigged I'm not sure it would be dejure rigged because there was no connection between the gamblers and the person doing the rigging.
An ordered deck is one arrangement from the set of randomly arranged decks. If the company ensures that decks are not ordered then they're not random. How can it be shown that the deck wasn't shuffled ... indeed if it can then the shuffling is non-random and this appears to amount to some sort of fraud in itself.
Do playing card manufacturers that sell shuffled decks make some sort of call on when a deck is not shuffled "enough". Knowing this information would allow more efficient models to be made for card counters, etc..
