Perhaps you're thinking in terms of explicit installer-side activation
of execution of these scripts.
But that's not necessarily necessary ;)

A convincing workaround would be to have these scripts executed
*unconditionally*, and then these would simply check whether a marker
is available (perhaps marker file stored on a temp fs).
So, IOW, the installer option would only need to have the capability
of creating those marker signals somehow (in case the user selected the
corresponding option),
then the unconditionally executed scripts would react on those (not) existing.

HTH,
