Maybe it relates to how cava works internally, from perlvar:

If the program has been given to perl via the switches -e or -E , $0 will contain the string "-e" .

Perhaps asking on the cava mailing list would provide clarification, I've never used it. Out of interest, have you given up on using pp?
