Handling 'behind' and 'in front' while keeping the 3D effect is actually quite easy, since some stretches of Z numbers always have exactly the same stereoscopy effects.

For example setting Z to 20, or 105, or anything in between, always gets one pixel's worth of stereoscopy no matter how high the 3D slider is, but a sprite with Z 20 is still in front of a sprite with Z 21, despite having the same stereoscopy.
