You need to tell XeTeX that to use Arabic script options in the font
table by using the option Script=Arabic in fontspec. If fontspec is
loaded, use:

\setmainfont[Script=Arabic]{Scheherazade}

if that's your main font. Because of different font technologies, Mac
users don't need to specify the script, but the rest of us do.
