MARC import reordering family/corporate creators

When importing MARC records as resources where 1) the primary creator
is in a 110 field (family or corporate name) and 2) there are
additional personal name creators in the 700 field, the agent records
are sorted such that the personal name creators from the 700 field are
listed first in the AS record. Since the MARC exporter takes the
first creator listed in an AS record and places it in the 1XX field,
we have the incorrect primary creator listed in the resulting export
and thus in our library catalog.

Ideally, I believe the importer could be tweaked such that the creator
name in the 1XX field would be given a sort preference in the newly
created resource record.
