There is a nice add-on or improvement to Ramani's original hack on sorting and display of search, label and archive results available here. Here is a description of the hack:
"My improved hack is based upon not showing the date at which a post is created, and make the posts indented as a nice bulleted list" - Hoctro
However if you do want the date header on the label search pages, just insert the line in red, in that code, as show here:
<b:if cond='data:blog.pageType != "item">
<ul><li><a expr:href='data:post.url'><data:post.title/> </a></li></ul>
In addition, if you are trying to get to terms with the beta blogger code (like me) and wish to understand more of it, there is a tutorial by Hoctro on defining and calling functions in beta templates. Do check it out here.
Ramani has come up with another hack. Blogger, by default limits the number of posts that can be displayed on a single page when a label's contents are viewed. This has been modified to show upto 100 results per page (useful if you have Ramani's search hack through which only post titles are shown instead of the entire post, on label and search pages). check it out here.
