If the programs have waived it I don't think I would re-take it, though I would send the old score despite it being expired.
Different schools are handling this differently. We are looking at GRE scores that come in, but are not requiring it due to the pandemic. In a case like this we would certainly look at the old score, which it sounds like she would want included.
I know there are some other programs that are not looking at GRE scores at all. In this case, the program would likely just toss the score, but she is no worse for sending it along.
So, I agree with the others, but I would send the old score (even if just unofficially) for those that do consider it.
