A little update if someone else needs to perform the upgrade with the 
changed XSLT - the lines also have to be swapped in the following file:

http://git.evergreen-ils.org/?p=Evergreen.git;a=blob;f=Open-ILS/src/sql/Pg/version-upgrade/2.12.6-3.0.0-upgrade-db.sql;h=7a865a89db22c333e8da9e3e7750bc9d1fc8bb95;hb=HEAD
