While I can see your position in relation to a jury verdict that had not yet been reduced to a judgment, Pennsylvania seems pretty clear on the enforcement of a judgment, a term that encompasses "a judgment or
order requiring the payment of money entered in any court which is subject to these rules, including a final or interlocutory order for payment of costs". Execution is permitted against real and personal property under the very next section,
Sec. 3101.1. Is there a statute, rule or case I should be looking at, under which the order described by the OP wouldn't fall under those provisions? I don't want to steer somebody wrong. While any states have provisions that can make things more difficult than this, certainly, but Pennsylvania seems to have removed unnecessary hurdles between getting an order for sanctions and enforcing that order.
