Especially given that the type of the list claims it to be "sorted",
insert_bundle() is a misleading name for a helper that merely
appends to it to make the list (tentatively) unsorted.
I am not opposed to "append all to make an unsorted list, then sort
the list at the end" strategy.

Usually compare(a,b) returns the sign of (a-b), but the returned
value from the above is the opposite. This is because we want the
list sorted from newer to older? It may help developers to name
such a (reverse) "compare" function differently.

If I were doing this patch, I would call the type of the list of
bundles "struct bundle_list" (without "sorted_" in its name), and
name the variable of that type used here "sorted". That would make
it more clear that this particular bundle list starts its life as
unsorted (with "append_bundle" function adding more elements) and
then gets sorted in the end, from the above several lines.
