  We report resonant x-ray scattering data of the orbital and magnetic ordering
at low temperatures at the Mn $L_{\rm 2,3}$ edges in \lsmo. The orderings
display complex energy features close to the Mn absorption edges. Systematic
modeling with atomic multiplet crystal field calculations was used to extract
meaningful information regarding the interplay of spin, orbital and Jahn-Teller
order. These calculations provide a good general agreement with the observed
energy dependence of the scattered intensity {for a} dominant orbital ordering
of the $ d_{x^2 - z^2} / d_{y^2 - z^2} $ type. In addition, the origins of
various spectral features are identified. The temperature dependence of the
orbital and magnetic ordering was measured and displays a strong interplay
between the magnetic and orbital order parameters.
