OK, to answer my own question - somebody else might find it useful; in order to make it compatible with Random Screensaver addon, just edit the adon.xml file and after line:
<extension point="xbmc.ui.screensaver" library="atv.py" />
add:
<extension point="xbmc.python.script" library="atv.py" />
<extension point="xbmc.ui.screensaver" library="atv.py" />
add:
<extension point="xbmc.python.script" library="atv.py" />
