Summary: 


Sailplane pilots most certainly do use the spoilers/speed brakes as
suggested.  For a number of reasons, you fly your approach at a speed equal
to or somewhat greater than best L/D (around 60 in a 2-32, for example),
which is substantially higher than 1.3Vso (around 30-35).  You use the
spoilers/speed brakes to accurately control the glide slope, and to correct
for the usual wind shear near the ground (diminishing head wind).
