Layer tags on areas are pure evil. The layer tag is there to indicate vertical separation, not to give a handy z-order hint to the renderer. So unless you do genuinely have two areas which are physically suspended one on top of the other then please don't add layer tags! Thankfully the mapnik maps will just ignore them. Instead you should fix the renderer, which may include adding something like handy_renderer_z_order_hint=1 to your objects if there isn't a better way.
