Seems like it should be really simple but all the ways I can figure out to do it are too kludgey.

It's rather easy:

for ($i=0; $i<count($arr); $i++) {
    if ($arr[$i][0] == $new_array[0]) {
        $arr[$i][1] += $new_array[1];
        break; // Optional - means the first "orange" found will be
               // updated only
    }
}

Small correction:

for ($i=0; $i<count($arr); $i++)
   {
    if ($arr[$i][0] == $new_value [0])
      {
        $arr[$i][1] += $new_value [1];
        break; // Optional - means the first "orange" found will be
               // updated only
       }
   }

But, I'm not sure as to why you (Brian) would want to do that anyway.
