There isn't a term I know of, but I can say that the chime bars on Gottlieb EMs are tuned to form a chord. You need the two lowest digits to be 99, then score 1 on the lowest digit. You get the 1 point, plus the carry-over to the tens, plus the carry-over to the 100s. From Sheriff onward, multiply scores by ten, because the chimes are tens, hundreds, thousands.
