Bug 34443: Spelling: Patron search pop-up Sort1: should be Sort 1

This patch instances of "Sort1" and "Sort2" being used
as labels in the interface, replacing the strings with "Sort 1" and
"Sort 2"

To test, apply the patch and test this page:

With the borrowerRelationship system preference populated, edit a
child record and click the "Add guarantor" button. There are two
fields in the form with the updated labels.
