I think something like this will work. Warning - really untested. 

my $sql = <<ESQL;
SELECT *,
       (name = 'Greg') + (age = 32) + (state = 'TX') AS score     
    FROM datable
    WHERE score > 0
    ORDER BY score DESC
ESQL

(how's that for a perl fig leaf? ;-)

Update: What was I thinking of? This looks much better, 

my $sql = <<ESQL;
SELECT *
    FROM datable
    WHERE  ((name = ?) + (age = ?) + (state = ?)) > 0
ESQL

You lose the score information and ordering, but that can be recovered in perl. You gain placeholders! as well as WHERE clause optimizations mentioned in replies.
