By default, I have sorting set to by Name, and when particular categories are selected, it's usually by Price. However, I am not sure how to assign a default sort-by setting when shopping by an option other than category. I have an attribute in my layered nav called "Size" and when that is used as the filter, I would like to sort by Price.
I guess the question then is if there is a way to do this in XML -- first how to call out the proper scope for a shopping option other than category, and second how to change the sort-by setting. I'm guessing though that it's not possible through XML and that I'll have to go deeper, but any advice is appreciated!
