I just recently did my timeline and was proud to figure out those darn apps :)
to move them in the order that you want...
1. Click your down arrow on the right of the app section (to see all 8 sections)
2. Than run the mouse over the "pencil" edit button on the upper left hand side of each app/photo of app
3. Than the first section, in gray, says swap with, click on anyone that is listed and it will swap...
easy enough... photos have to be first you can not change that! :)
