I can't see any other way than listing the possible cases and finding the total score for each case. Using the first letter of each outcome, we could have
BBBB -- 36
BBBS -- 34
BBBT -- 31
BBBO -- 28
BBSS -- 32
BBTT -- 26
BBOO -- 20
BBST -- 29
BBSO --
BBTO
etc, watch for duplication of totals

bullseye 9
second circle 7
third circle 4
outer circle 1
