A: The order of the columns in the Summary Stats is the same as in the Data>Select Variables dialog.  Swapping axes will reset the order of variables/statistics.  To change the order of statistics, it is possible to switch the axes using the switch icon on the RHS toolbar (while the summary statistics window is active) and have the variables as rows and the statistics as columns.  However, to keep the order chosen, the cells will have to be copied in this transposed format.
