At about 8 or 9 high schools in my area, they pay the officials to do the timing. We never do the scoring. Ususally it is the JV official (or an injured varsity official that can't ref), doing the clock and we wear our stripes. One of the down sides to this is that people at the table ask us if we agree with the call, or to explain a call. I tell them we never, ever, miss a call
If you don't believe me, just ask me! We get $25.00 for a varsity game and $30.00 during district/region playoffs.
