Arabic interface files selection problem

When using arabic user interface (and probably any right to left language), files and folders are not selected in the expected order when navigating using the keyboard. They are still sorted correctly.

For example, assume we have 11 files named from 1 to 11 in a certain directory sorted alphabetically. They are displayed correctly from right to left, top to bottom like this:

4 3 2 1
8 7 6 5
 11 10 9

however, if I press "Home" button which should select the first file, file "4" is selected instead of 1. If I press "End" button, file 9 is selected instead of 11.

Also when using arrow keys, I expect pressing "Left" while on file "4" changes to file "5". However, nothing happens as if file "4" is the first file and I am going backwards.
When I press "Right" button while on file "1", I expect nothing to happen since I am in the first file and I am going backwards. However, file "8" is selected instead as if it is after file "1".
Similarly, if I press "Right" while on file "5", file "11" is selected while I expect to select file "4" as it is located before file "5".

Thank you very much
