You have two options - copy the song and then modify the page order to only include the pages you want, or load the song, tap the center of the screen to bring up the overlay, tap the circle at the bottom left and then click "Create Snippet". You can then enter the pages you want to use from the song. The "Create Snippet" feature effectively does the same thing, although you can choose not to include annotations and such.
