I seem to remember that the general consensus was that Press Releases weren't a great tool for pure SEO. However (this was pre-Jagger, just haven't got round to posting about it) I had a jump in certain rankings, and the only thing that had changed was a recent period where there was a sustained press release campaign.
The sites that publish press releases generally either do so on one page or a few pages, and then overwrite those press releases with new ones as time goes by, and other sites publish press releases on new pages, never overwriting the old ones, but perhaps moving them to archives. In the former case, the links you get from these are termporary, in the latter case they are relatively permanent.
