I think he was asking for when to use them, not order of application.
Here's my view:

route-maps are a must when an action has to be attached to a criterium.
They are used in many places, and the match criteria can be many things
included ACLs and prefix lists.

prefix-lists is the "new way" for matching routes, aka prefixes.
They are much more self-evident (once you get the idea) than ACLs for
routes (extended ACLs using destination as mask). Also they support the
CIDR slash notation, which is nice.

ACLs for everything else, like security filters, and to let lab writters
make puzles on "do this in just one line" :-)

HTH.
