I am pretty sure you have to report both scores.
From PTCAS:
A: Enter data for all complete and planned test dates on the PTCAS application and arrange for your official GRE scores to be sent directly to the programs, if required. If you request official scores to be sent to one or more programs, ETS will automatically send all of your GRE scores for the past 5 years. Not all PT programs require the GRE for admission.
This is the response to "What if I have taken the GRE more than once?"
Hope this helped 🙂
