Page Menu Bar Sorting

Once I saw the theme Atahualpa, more than any theme I do not want to use.
But there is a problem.
How to sort the pages? I have it sorted only in alphabetical order:
1.Abcd
2.Bcde
3.Cdef
...

How to do it? :
Cdef
Abcd
Bcde

Used plugins pageMash and My Page Order
http://wordpress.org/extend/plugins/pagemash/
http://wordpress.org/extend/plugins/my-page-order/
Does not work!

What can you do to earn these plugins?

Can I as a manual in the files of the theme, to change something, to change the order of the sequence number of the page?

AND another important question(!):
In a theme file output page? "wp_list_pages" I have not found! where and how?
