Answer:
I have been waiting for decades to locate Social Tea cookies. I have not been able to find them anywhere. However, as recently as last week, I found the old Social Tea cookie clone: Leibniz' Butter Biscuits. If the reincarnation of Nabisco's wonderful cookie is really as disgusting as you say, try Leibniz (from Hannover, Germany). I found them in my local Smith's grocer (Ralph's/Kroger's), and am totally delighted.
If your grocer does not carry them nor is able to order them, here is the information on the package:
Leibniz
Quality since 1891
Butter Biscuits
