I think the JSFOnAS7 page is correct in reporting Mojarra 2.0.4-b09.
The difinitive place to look is in the main pom.xml of the source bundle. That will tell you the exact version of any artifact for any AS7 release.
I don't think so:
META-INF/MANIFEST-MF in modules/com/sun/jsf-impl/main/jsf-impl-2.1.3-b02-jbossorg-2.jar contains "Bundle-Description: Mojarra JSF Implementation (javax.faces/2.1) 2.1.3 (20110825-SNAPSHOT)"
