If you're using My Pictures Slideshow you get the pictures in random order.
As far as I know you cannot change this.
To use personal pictures as a screen saver
1. Ensure that you have two or more pictures in a folder on your computer.
You can upload pictures from a digital camera or scanner, or copy them from
the Internet or an e-mail attachment.
2. Open Display in Control Panel. Or right click the Desktop, select
Properties and click the Screen Saver tab.
3. On the Screen Saver tab, under Screen saver, click My Pictures Slideshow
in the list.
4. Click Settings to specify the folder containing your pictures, define
picture size, and set other options.
Notes
* To open Display, click Start, point to Settings, click Control Panel, and
then double-click Display.
* My Pictures Slideshow scrolls through all the pictures in the folder.
* After you specify a screen saver, it will automatically start when your
computer is idle for the number of minutes specified in Wait.
* Click Preview to see how the selected screen saver will appear on your
monitor. Move your mouse or press a key to end the preview.
