Whether the torque is plus or minus depends on the sign convention you use. If you take counterclockwise torques as negative, then the z axis is positive going into the plane of the page. If you take counterclockwise torques as positive, then the z axis is positive coming out from the plane of the page toward you. By convention, the z axis is usually considered positive coming out from the plane towards you, hence, countrerclockwise torques are positive (right hand rule).
Personally, I despise the cross product definition of torque, and use it only when absolutely necessary. It is often simpler to break the force into its x and y components, then the torque of each component force about the point in question is the component force times the perpendicular distance from the line of action of that force to that pivot point, then just algebraically add up the torques from each force component, ccw is +, and cw is - . In your example, both components produce ccw torques, so they are additive.
