I'm not sure, if I understood yor problem, but could the following be a solution:

create table sort_table (sf int, value char(1));
insert into sort_table(1,'C');
insert into sort_table(2,'A');
insert into sort_table(3,'B');

select y.INDEX, y.VALUE, s.sf from your_table y, sort_table s where y.value = s.value order by s.sf;
