%%%Checker deselect doesn't work with edge ring.
In vertex select mode it's not possible to select an edge ring and it doesn't look like a way to select every Nth edge. Vertex sorting hasn't helped with that, though I'm not very familiar with it so I can't tell if I did it correctly.

How to test:

Open Blender, add a cylinder (cap or not)
In edit mode, switch to edge select mode and select the edge ring around the cylinder (ctrl+alt+RMB)
Select menu -> checker deselect

Tested with Blender 2.63, 2.66, 2.66.1 r55038 on Linux, 32-bit.

%%%I found the same problems.
First i found 'Select Every N Number of Vertices' change name to 'Checker Deselect' .
And I use sphere , one mesh edit mode ,Edge select, select a vertical edge and use Select -> Edge Ring to select a edge ring,
and then i use Select->Checker Deselect , and found it not worked .
test with blender 2.66a Linux 64-bit and windows 64-bit . %%%

%%%This isnt a bug, since the tool is working as intended and there is no mistake in the tool logic that causes this to fail.
for the tool to work as you suggest it would need to be extended to support this case.

This could be supported by adding special support for boundary edges or deselect edges by stepping over connected faces rather then edges.

%%%I've found a way to do this with the checker deselect tool.

First select the edge ring and an edge loop to connect the ring's edges (Ctrl-Alt-RMB for the ring and Shift-Alt-RMB for the loop).
If your edge ring is closed (ie. a cylinder), deselect one of the loop's edges to make the selection open.
Use the checker deselect. It deselects every second edges for both the ring and the loop.
Deselect the remainings of the loop by clicking on one of its selected edges with Shift-Alt-RMB.
If the first edge of the ring is incorrectly (de)selected, correct it.

This works for one edge ring and for two connected parallel edge rings too if you select the loop between the two rings.

This feature would be great for rings because it is ideal to evenly reduce polygons on a cylindrical surface.%%%
