In theory I would think it would, until the eZine folks got complaints or saw what was being done and began nixing accounts and articles because of it.
Something less risky and faster in my opinion would be to setup a strategic social bookmarking plan for your article pages.
eZine pages rank great in the SERPs on their own, especially if you're targeting low lying keyword fruit. For harder terms tag the article with your keyword on a couple dozen bookmarking sites.
For additional link-chaining grab the URL's of your account feeds from the bookmarking sites you use (most provide rss feeds for each account) and run them all through R$$ Submit (you can find it here I think).
Those feeds of your tags will contain direct links to your article, and rss is never nofollow... so well worth the couple of minutes it takes to run a batch of feeds. This is also why bookmarking on sites that are nofollow is still very useful, if you get a feed there you've got ******** links to syndicate from it.
This will give you tons of inbound links from rss directories and web 2.0 authority sites to your article(s), takes almost no time at all and can have a near instant effect on SERPs.
I've had articles indexed in under an hour and top 5 on Google against over a million competitors on the same day doing this.
I'm not saying don't use pr$torm, but I'd limit its use to be safe and maybe do it after all of the social bookmarking and rss submissions.
