We added numbers to page titles in a hyper competive industry sucessfully in order to diiferentiate from competitors. We added the counter not just to the title but also in the meta description and incorporated it into the page content to. I would recommend the format:
<title>Crazy Asteroid Photos - 33 Photos of Crazy Asteroids </title>
Our counters didnt change more than once a month and we only saw positive results.
