Hi, Gez,

What I'm imagining is a command executed on a headline to insert a
property into each of its children "fixing" the current order;
something like ":sorted:01", ":sorted:02" etc.
I think this is a neat idea, and can see some uses for it for my own stuff. I've made a first pass below. Please test it and let me know how it works for you (and please *don't* test it on anything valuable without backing up first!).

Code follows.

"Store the outline of the subtree of the entry at point by
setting the property PROP of each direct child entry to its
current position in the tree. With prefix ARG, store the position
of the whole subtree. The tree can be restored to the stored
outline by sorting on the property with `C-c ^ r'. Note that this
will only work properly on the order of each subtree; if headings
are demoted, promoted, or moved into different subtrees, the
result may or may not be nonsense, but it will be impossible to
restore the original order by sorting."
