[Plugin: My Content Management] Random sort order?

Is there a way to select a randomized sort order? If not, that would be a very helpful new feature, for example to display one randomly selected testimonial in a widget using a shortcode such as “[my_content type=’testimonials’ display=’full’ count=’1′ order=’random’]”.
