Oh I see.  In that case, what you want is something like this:

\score {
        <<
                \new GrandStaff <<
                        \new Staff = "guitar traditional" <<
                                \clef "treble_8"
                                \context Voice = "upper" \upper
                                \context Voice = "lower" \lower
                        >>
                        \new TabStaff <<
                                ... % what you had before
                        >>
                >>
                \new PianoStaff <<
                        \new Staff = "piano righthand" <<
                                \clef treble
                                ... % piano notes here
                        >>
                        \new Staff = "piano lefthand" <<
                                \clef bass
                                ... % piano notes here
                        >>
                >>
        >>
}
