Erm, it's a national park now, not a monument.

Plague is rated 5.10a, not 5.9... and while I think it's a fun route I don't feel it is at the same star level as the other routes you listed.
Lava Falls, Little Javelina, Wet Kiss - all great routes.
Coyote Ugly would be on my list of top 5.9 routes at Pinnacles too - a spicy lead and fantastic views from the summit.
Lava Falls is my favorite of all those - hard to top the fantastic climbing, length, and exposure on that route.
