 The basic idea is that things on top cover up things beneath them.  The potentially confusing part is that Inkscape implements this in two ways: layers and levels.  Levels are what order objects are in within a single layer.  So the highest level object is still below all of the objects in the layer above it. <link linkend="document.layer_change_level">layer_change_level()</link> changes the order of layers and <link linkend="document.selection_change_level">selection_change_level()</link> changes the order of objects within a layer.

-Changing the level of a selection also deserves some explanation.  The <link linkend="document.selection_change_level">selection_change_level()</link> function can work in two ways.  It can be absolute, "to_top" and "to_bottom" work like you'd expect, sending the entire selection to the top or bottom of that layer.  But it can also be relative.  "raise" and "lower" only work if there is another shape overlaping above or beneath the selection at the moment.  Also if you have two objects selected and they are both occluded by a third, raising the selection once will only raise the first object in the selection above the third object.  In other words selections don't move as a group.
