After reviewing some old bugs linked to my launchpad account... I have some good news!
This behavior seems linked to the workaround for bug #348934
I realized today that I had the "Legacy Fullscreen Support" in compiz config settings manager selected in order to fix a bug in mythtv where gnome-panel was showing above mythfrontend in full screen mode.
The good news is that since I'm no longer using gnome-panel, I have no need for this workaround. After disabling the "Legacy Fullscreen Support" in compiz config manager, cairo-dock shows above all windows again!
I tested both with mythfrontend and the realvnc client, and was unable to get cairo-dock to appear below windows.
