To arrange the order of the songs on your burned CD, click on the playlist name to view the list of songs. When you see the list of songs, you can drag and drop them to put them in whatever order you want.
If you're making a copy of a single CD, you won't need to rearrange the songs - iTunes will maintain the CD's original track order.
NOTE: If you want to burn a gapless CD, follow these instructions.
