You don’t need to apply ED to Penn with your numbers, but if that’s your first choice, you might as well. You won’t get scholarship money at Penn with those numbers. General rule of thumb: Both GPA and LSAT must be above 75% to be considered for scholarships.
Good god, don’t waste that GPA on that LSAT. Retake. And, yes, it’s definitely an option for you. No one is going to shoot you if you take the test again. You have a GPA worthy of YHS or a $150K+ scholarship at Penn or another T14. Putting in three months of study and retaking could easily save you over two hundred thousand dollars in loan repayments. Don’t be a fool.
