Thanks for both. I don't seem to know how to use the new for loop. I am trying to modify your previous template to this:

program:
	all_authors = category_items('authors');
	res = '';
	for a in '&' all_authors:
		ratings = from_search('rating', strcat('rating:true and author"=', a, '"'));
		if ratings then
			avg = divide(mean(ratings), 2);
			res = list_union(res, strcat(a, ':', avg), ',')
		fi
	rof;
	res

Obviously I am doing something wrong (and probably silly) here.
