I haven't checked the code but a typical source of incompatibility between stock and JiffyDOS KERNALs are the interrupt handling. Programs that copy the subroutine calls from the original KERNAL interrupt handler will fail because the tape checking (which also calls some timer handling routines) routine is not there.
At least this is the case with Domino (and it has been fixed in Domino Deluxe) and also with Leaper.
