You're right. The global variable namespace is strictly limited to the
tree of scripts created by the the "include" extension. No variables are
shared between scripts executed in the multiscript sequence
(http://tools.ietf.org/html/draft-degener-sieve-multiscript-00#section-4).

A bit ugly, but I guess it would work.

One big issue with this is that the user can choose not to include the
script.
