You've made the main points I was going to make, but, for what it's
worth, I was going to suggest this:

  function arrCompareSmaller(A, B)
  {
      var alen = A.length, blen = B.length;
   
      if (alen == blen) {
          var i = alen - 1;
          while (i >= 0 && A[i] == B[i]) --i;
          return i >= 0 && A[i] < B[i];
      }
      else return alen < blen;
  }

and remark that the OP seems to be ignoring negative numbers, but I
don't suppose he's bothered by that.
