As no-one else will be bothered to look up the ANO, I have had a peek and copied out the sections below.
Unless somebody can demonstrate either from these or elsewhere that a glider pilot cannot fly in cloud in class G, it seems to me that the exemptions highlighted * - - - * (my markings) make the point about the difference between a PPL with no other ratings in a powered aircraft, and a glider pilot in a glider.

* 'Glider' means:
(a) a non-power-driven heavier-than-air aircraft, deriving its lift in flight chiefly from
aerodynamic reactions on surfaces which remain fixed under given conditions of
flight; and
(b) a self-sustaining glider;
and a reference in this Order to a glider shall include a reference to a self-sustaining
glider; [ ANO as amended by SI 2003/777]
'Instrument Flight Rules' means Instrument Flight Rules prescribed by the Rules of
the Air;
'Instrument Meteorological Conditions' means weather precluding flight in
compliance with the Visual Flight Rules;
