Hi Steven,
Adding a specialization for iter_swap

namespace std {
void
iter_swap(ziterator a, ziterator b)
{
std::swap(a->get<0>(), b->get<0>());
std::swap(a->get<1>(), b->get<1>());
}
}
solved the problem for std::random_shuffle.
For std::sort I provide a comparison functor for the tuple.
but the compiler (VC8) complains about no match for _Rotate
Any hint would be appreciated.
