ok thanks.

But out of curiosity..

Does the {'op} on its own, need to be treated as grammatically singular or plural ?

I don't think we know for sure. The gloss given in the back of KGT is

{'op} some, an unknown or unspecified quantity (n)

Since the gloss uses "an", you could make a small but nonzero argument that it should be singular.
