I'd start with something like:

  (:if expr    ( ! equal "{=$:Work}" "{<$:Work}" ) \
            || ( ! equal "{=$:WAuthor}" "{<$:WAuthor}" ) :)

Since the page text variables are actually in the Data-
group instead of the current group being searched, I'm guessing:

(:if expr ( ! equal "{Data-{=$BaseName}$:Work}" "{Data-{<$BaseName}$:Work" ) \
          || ( ! equal "{Data-{=$BaseName}$:WAuthor}" "{Data-{<$BaseName}$:WAuthor") :)

Don't forget the "expr" conditional to (:if:) when doing a
multi-tested conditional such as this.
