Umm, there's no difference how you wind it. 

Say, you wind it counterclockwise. Then once it is finished you turn
it over (bottom up, top down), and voilą, you've got a clockwise wound
secondary now. ;o)

Also, in the end, there's no difference in which way round you place
the coil into your TC system, performance wise. The signal will always
be AC sine wave, you don't get an "positive" or "negative" topload. 

But, in a twin TC coil, the winding sense in which the secondaries are
placed does play a role. They have to be placed so that, considering
primary coil winding directions, the output will be 180 degrees phase
shifted - this is if you want to have the streamer breakouts between
these secondaries. If the streamers should repel each other, you'll
have to place that way round so you get 0 degrees phase shift.
