Hi Wu, std::sort is only used by RenderBin's when they need to sort into depth order, otherwise they just use the state sorted order provided by the state graph. When std::sort() is used keys of 0 will always appear before 1. The only difference with std::stabe_sort is that if there are two 0 values then it preserves the order, while std::sort makes no such guarantee.
