Quantum Espresso: what is the order, in terms of orbitals, in which occupations are to be specified in the pw.x input file?

05 October 2015 0 2K Report

For an isolated atom calculation, the occupation for various orbitals needs to be specified in the OCCUPATIONS card, in the input file (or so I believe. It wasn't converging otherwise). But what order should I follow while giving them? Is it using the l quantum number, or the Aufbau principle? Also, should I include all the orbitals used in generating the pseudopotential I'm using?
