D'oh. That brings my idea of working in reverse up to 133. 
sub hole {
$i=$s=0;$s-=$_[-1]if"@_[-2,-1]"=~m!/|X!;map{$s+=$_[$i-1],$_=/X/?($s+=$
+_[$i-2],10):10-$_[$i+1]if/\D/;$s+=$_;$i++}@_=(0,0,reverse@_);$s
}

    Short though this is it fails the test suite 

    print score(qw(5 / 6 3 X X 7 0 4 3 X 4 / 8 1 3 / 6)),"--> 146\n";
print score(qw(X X X X X X X X X X X X)), "--> 300\n";
print score(qw(0 / X 0 / X 0 / X 0 / X 0 / X 0 /)),"--> 200\n";
print score(qw(X 0 / X 0 / X 0 / X 0 / X 0 / X 0)),"--> 200\n";

sub score {
$i=$s=0;$s-=$_[-1]if"@_[-2,-1]"=~m!/|X!;map{$s+=$_[$i-1],$_=/X/?($s+=$
+_[$i-2],10):10-$_[$i+1]if/\D/;$s+=$_;$i++}@_=(0,0,reverse@_);$s
}
__END__
146--> 146
330--> 300
210--> 200
210--> 200

      Grrr. All of the way up to 175: 
      sub score {
$i=$s=0;map{$b=!(++$i<5&&$_[4]eq X||4>$i&&$_[3]eq'/');$s+=$b*$_[$i-2],
+$_=/X/?($s+=$b*$_[$i-3],10):10-$_[$i]if/\D/;$s+=$_ if$b}@_=(0,0,rever
+se@_);$s
}

      Note that this does not pass the final test in your suite, but the score given in the final test cannot come from a real bowling game. Remove the trailing 0 that I am sensitive to and I pass.

      Ah well. Yet another cute idea killed by horrible boundary conditions.

    This appears to fail on runs with a spare or strike in the bonus balls, e.g. 
    qw(1 0 2 0 3 0 4 0 5 0 6 0 7 0 8 0 9 0 X X 0) -> 75 should be 65
qw(9 0 9 0 9 0 9 0 9 0 9 0 9 0 9 0 9 0 9 / X) -> 111 should be 101
qw(X X X X X X X X X X X X) -> 330 should be 300
qw(0 / X 0 / X 0 / X 0 / X 0 / X 0 /) -> 210 should be 200
