Woody's judge is correct. You get an overall score on all the items in the box, assuming their is enough for each judge to get a sample. And you always want to have enough of each type of meat for every judge to try, otherwise you can get really weird scores that are hard to interpret.
For a hypothetical example, if you turn in a box with three slices of brisket and three burnt ends, what can you deduce if your scores vary widely from judge to judge?
The "bone in" rule applies to each item in the box. All KCBS meat rules apply to all portions not just some. So if you had boneless rib tips included, the box would be deemed a DQ, just as if you had a pork box that had pulled from a wholely cooked butt plus slides from a parted and then cooked butt.
