Given a relation that contains this:

({(11),(9)})
({(8),(7)})

Is it possible for me to SUM the contents of each bag so I get:
(20)
(15)

Thanks,
James

Sorry if I've misunderstood the question but isn't this exactly what the
builtin function SUM does?
Given that your relation is contained in the alias 'in' and has this schema:
grunt> describe in;
in: {bagdata: {(int)}}

you could do this:
grunt> out = foreach in generate SUM(bagdata);
grunt> dump out;
(20)
(15)
