Cakephp 1.3: Find and sorting depending on wich field is the matching

Hello everyone. This is my first question here. I would appreciate it if you could help me with this question.

I am interested in being able to sort the results of a search using as a sort criteria which field/s matches with the condition.

A simple example, I have a table of products that contains the fields: title, description … a simple search would look like this:

    $products = $this->Product->find('all', array(
        'conditions' => array(
            'Product.title LIKE' => '%'.$keyword.'%',
            'Product.description LIKE' => '%'.$keyword.'%',

I’m interested in having the results in this order:

1st: Records containing $keyword in title field and description
2nd: Records containing the $keyword only in the title
3rd: Records containing $keyword only in description

How do you propose to make this query to work on a cakephp 1.3?

Many thanks!!!
