The $(command) notation should also work in any modern Korn shell
implementation.  It was specified in both POSIX and SUS (backticks are
actually deprecated).  I don't think it works in csh, but then again,
scripting in csh should be illegal anyway, as it has some broken
behaviors that can bite you badly with scripting.  tcsh does fix many
of them, but I still wouldn't ever recommend using it for scripting.
