7.3 addresses this by adding another field to that table.. ie: 'GRAEMLIN_SORT_ORDER'
as for 7.2.2 the easiest way would be to quickly add that field in your table and then manually use phpMyAdmin and put the numbers in the order you want.. this replaces having to write an admin cpanel interface for it..
then just change the query in ubbthreads to add 'ORDER BY GRAEMLIN_SORT_ORDER' and *poof* done..
might be easier for you to wait for 7.3 ?
