%%%The "Sensor" physics mode in BGE uses the "use_actor" property to determine whether to filter for actor collisions, or to accept any collision.
The UI option to toggle it is missing from the Physics tab > physics rollout in BGE.
Turning it on from the python console, or by adding a control for it to properties_game.py works as expected.

This option was present in Blender 2.4x but is missing in Blender 2.62, though the wikidocs still list it.

%%%"Detect Actor".

In sensor objects (physics mode: sensor), the OB_ACTOR RNA property ("use_actor" in python) is overloaded to mean whether the sensor reacts to any collisions, or just to actor objects. ( source\gameengine\Ketsji\KX_ConvertPhysicsObjects.cpp - lines 486-488 )

So release/scripts/startup/bl_ui/properties_game.py needs to have an option for physics_type=='SENSOR' that includes col.prop(game, "use_actor", text="Detect Actor")

It needs different text since in this case, the use_actor setting is doing something different (determining whether or not the sensor is doing broadphase filtering for actors)

Like so:
