I know that ping_group is treated as one ping_host score wise. I expect the score to be 500 for that.

Ah, ok. so its better to change this to:

<meta_attributes id="group_1_instance_attrs">
	<attributes>
		<nvpair id="group_1_target_role" name="target_role" value="started"/>
		<nvpair id="group_1_resource_stickiness" name="resource_stickiness" value="200"/>
	</attributes>
</meta_attributes>

And the score of 200 counts for every primitive in the group. Ok, so it's 800. I thought it counts only one time.

Apart from my misunderstanding here with 4*200 score, does my setup work score-wise now? Or do I miss anything?
