コッチの場合 //post/@id か。これを GM_setValue すればいいのだろうけど、発火するたび、取りにいくのはマズイよなあ。AutoPagerize の SITEINFO がどうやっているか見てみるか。もしくは youpy の wedata utility。

function summerFilter(doc, url, info){
  var content_element = $X('id("posts")', doc)[0];
  content_element.className = 'autopagerize_page_element';
  
  var a = $X('id("pagination")/a[contains(text(), "Next page")]',doc);
  if (a.length) a = a[0];
  else return;
  r = Math.floor(Math.random() * GM_getValue('postno', ' 83297833'));
  a.href = 'http://www.tumblr.com/dashboard/1000/' + r;
  a.className = 'autopagerize_nextlink';
  a.rel = 'next';
}
