Hoe do you define "importance"?
You can order the results alphabetically/numerically on as many columns
as you like - for example,
select ....
where title = ....
order by title, summary
will order the results on title first, then summary... though you
probably know this and I'm misunderstanding what you need.
A little more detail will help.
