Scouting - does it show items on Adventure map?

[BB Shockwave]

One of the nice new things in AP was that on the adventure map, you could now see items (runes, gold, crystals, scrolls) shown with a small gold star - that way, I did not miss any stuff obscured by trees or rocks.

I always thought this was dependent of you having level III Scouting, but in Orcs on the March, I got to this skill level and the map still doesn't show anything... So, how does this work?
