Wohoo, it's working! Thanks!

Just for anyone looking this up later, you forgot the parentheses:

(add-to-list 'tramp-default-proxies-alist
            '("B" nil "/sudo:address@hidden:"))
(add-to-list 'tramp-default-proxies-alist
            '("A" "root" "/ssh:address@hidden:"))

(I dropped the username in the first rule, then it seems I can just do
a "/ssh:B:/somepath" without username)

I think I can follow the logic now - the command is to ssh to B, when
accessing B we must first sudo to root at A, when accessing A as root
we must first ssh to A. It's a bit confusing because it's backwards,
and I think I didn't quite grasp the rule would fire on the sudo too,
the info page is talking about hosts and whatnot. :)
