I added a tweak to control the order of categories in the tag browser. It is available in source now and will be generally available in the next release (0.8.41). The tweak category is "Control order of categories in the tag browser". The tweak documentation is under the spoiler.

Spoiler:

# Change the following dict to change the order that categories are displayed in
# the tag browser. Items are named using their lookup name, and will be sorted
# using the number supplied. The lookup name '*' stands for all names that
# otherwise do not appear. Two names with the same value will be sorted
# according the the default order; the one used when the dict is empty.
# Example: tag_browser_category_order = {'series':1, 'tags':2, '*':3}
# resulting in the order series, tags, then everything else in default order.
tag_browser_category_order = {'*':1}
