Neither - they're not twiners, they have modified leaves called petioles, which are like very thin, flexible growths that latch round a thin support and curl up tight to support the main growth, much like clematis does. This means, obviously, that runner beans/sweet peas need thin supports or mesh to support themselves, not trellis, on which the lathes are too thick, unless they're those thin, willow type ones.
To answer your question about twiners generally, all twine clockwise - except for Bindweed.
