4 possibilities


 * Zoro's brain works like Log Pose. It picks up electric signals from electric fields of other near by Islands and just walks in that direction.


 * Zoro traded his sense of direction for his incredible luck.


 * Zoro's brain has no control over his legs. The command line between his brain and legs much have been cut.


 * Zoro follows the direction in which the clouds look larger. When the sky is clean he stops and takes break.

I will let you know if I get more reasons >_O
