Yes. In the court order section 5 (on line 8 of page 3) "Apple shall advise the government of the reasonable cost of providing this service."
Perhaps only engineering resources. (it's always gonna be a big legal hassle)
A reasonable cost may still be $150 to $200 per hour. Engineering time charged to a third party is never cheap.
Yeah. This may end up costing a huge amount with no results. Apple (and it's employees) doesn't have much incentive to crack the device although someone might be curious and use this as a good time to look for security holes on the government's dime.
