Scouts have Trapfinding, too, actually... And Disable Device. Though not Open Lock or Use Magic Device.
I was especially wondering about the Skirmish vs. Sneak Attack ability. I've never seen a Scout in play, so I was wondering how moving 10 feet worked out, considering the Scout could never take a full attack with its Skirmish ability, whereas a Rogue can with Sneak Attack. That seems like a pretty huge difference right there.
I noticed that a common variant for Rogues was to allow Sneak Attack to be replaced with a Bonus Feat - which I was planning on implementing, if the Rogue in the party wanted to use it. Would allowing such a variant for the Scout's Skirmish ability be overpowering, or does anyone think it would be balancing to allow that, too?
Like I said, I've never seen a Scout in play. I don't know quite what they're capable of, as compared to a Rogue. On paper, they just seem potentially less useful. But maybe that's just dependent on the situation, which I haven't seen yet.
