Before you use it: pdb.gimp_context_set_interpolation(interpolation). In practice the code in your plugin should be  bracketed by pdb.gimp_context_push()/pdb.gimp_context_pop() (or gimp.context_push()/gimp.context_pop()) so that any context changes don't change general settings.

IIRC the default one in 2.8 was "Cubic" but I could be wrong or you could have changed it.
