Keep in mind that we are dealing with AC waveforms, and so the directions of conventionally-defined current flow and magnetic flux lines are continously reversing.
Twisting will affect a number of electrical properties (not necessarily to an audible degree), including inductance, capacitance, bandwidth, the degree to which abrupt changes in current may be resisted, noise pickup, and noise radiation. I cannot envision a reason, though, why the direction of the twist in an AC power cord would make any difference, or at least a difference that is consistent and predictable.

It is my understanding that Current & Magnetic field flow through wire in a clockwise direction.Current does not flow either clockwise or counter-clockwise. A magnetic field does not flow through a wire, it surrounds the wire in a direction defined by the right-hand rule with respect to the direction that conventionally-defined current is moving along the length of the wire.
