Blogger.com post display question

(I already asked this over at the proper Google forum, but that place is like a black hole where posts go to die unanswered. So here it is again.)

I want to have a link on my blog sidebar to a list of all posts of one
type – but in chronological order, not reverse chronological order,
as is the default.

Now, I know that this is the way a basic label URL looks:


http://www.myblog.net/search/label/mylabelname

And this is how one sorted by published date (rather than last-edited
date) looks:


http://www.myblog.net/search/label/mylabelname?orderby=published

But how to put it so that the earliest post comes up at the top of the
page? I want readers to be able to access a series of posts from first to last, in the order that they appeared.
