  We prove the formality and the evenness of odd-degree Betti numbers for
compact K\"ahler orbifolds, by adapting the classical proofs for K\"ahler
manifolds. As a consequence, we obtain examples of symplectic orbifolds not
admitting any K\"ahler orbifold structure. We also review the known examples of
non-formal simply connected Sasakian manifolds, and produce an example of a
non-formal quasi-regular Sasakian manifold with Betti numbers $b_1=0$ and
$b_2\,> 1$.
