Book and score title are dealt with in a special way: when they
are interpreted, the header variables are added to the properties
provided to the command, which can then retrieve the header
variables.

This is not the case of other markups. You may work around that
by using variables defined in the paper block, and then retreiving
them using the command layout argument.
