When you are talking about how a track is wired polarity actually refers to the direction that electricity goes through the controllers, not the direction the cars will run on the track. 1/32nd and 1/24th tracks are wired so that the right hand rail is positive looking in the direction of travel.

This is what is referred to as positive polarity.

As you described things in your first post for the cars to go left the rail closest to you would have to be negative. I can't recall seing a motor that was marked with positive and negative wires. As has been said before a lot of motors made for 1/32nd scale cars have neutral timing and will have the same performance no matter which direction they are run. Looking at the motor from the endbell end the right hand connection has to go to positive if the pinion gear is on the endbell end.

What end of the motor is the pinion gear on? If the pinion was moved to the opposite side the wires would have to be reversed. Another option is to open up the motor and swap the magnets around.
