Here is a script which does what you want:

=== ===
let main () =
   Dynamic.Parameter.Bool.on "-wp" ();
   Dynamic.get ~plugin:"Wp" "run"
     (Datatype.func Datatype.unit Datatype.unit)

let () = Db.Main.extend main

$ frama-c-gui -load-script run_wp test.i

If test.i is your original example, all the properties are valid.

One additional remark: if you remove the call to Dynamic.get in this 
code, it is possible to observe the same behavior, but it is only by 
chance: it is not specified that the main of this script is executed 
before the main of the WP plug-in which looks at the value of -wp in 
order to run the WP calculus. Hence the second function which forces the 
execution of WP after setting -wp.

Hope this helps,
