It's a tough call because our Solar system is tilted some 60 degrees to the plane of the Milky Way. Any designation of "north" or "south" is purely arbitrary, as are the notions of "above" and "below". I wouldn't be surprised to learn that our galactic "north" was chosen so that it would appear to turn anticlockwise when viewed from that direction.
The same can be said of other galaxies.
The direction of rotation and revolution of bodies in our solar system came primarily from the rotation of the gas cloud from which it condensed. The Milky Way's rotation speed is too slow to have any noticeable effect on something that small.
"For shame, gentlemen, pack your evidence a little better against another time."
