Problem description: 
When I print handouts, the order of the slides is always top to bottom and then to right, whatever option I chose in the "order" option on the "Page Layout" tab.
Steps to reproduce:
1. .... Open a presentation with many slides
2. .... Configure the handouts for 6 slides per page
3. .... Print the handouts with "left to right, then down" order on the "Page Layout" tab.

Current behavior: If the slides are in the order 1,2,3,4,5,6
they are laid out as follows on the printed page:
1    4
2    5
3    6
Expected behavior: They must be
1    2
3    4
5    6

You can select any order option on the "Page Layout" tab, it has absolutely no effect on the printed layout.
