Your solution returns the following results:

qw(5 / 6 3 X X 7 0 4 3 X 4 / 8 1 3 / 6)
146
qw(X X X X X X X X X X X X)
300
qw(0 / X 0 / X 0 / X 0 / X 0 / X 0 /)
0 (should be 200)
qw(X 0 / X 0 / X 0 / X 0 / X 0 / X 0)
0 (should be 210)

And, in subroutine form, I count 192. (My counts were off cause my window wasn't 80 characters wide. Fixed now. *blushes*)

Update:

qw(0 / X 0 / X 0 / X 0 / X 0 / X 0 /)
0 (should be 200)
qw(X 0 / X 0 / X 0 / X 0 / X 0 / X 0)
172 (should be 200)
