[XeTeX] Problem with Sanskrit2003 and XeTeX

I was not able to reproduce that behaviour. With your minimal example,
the glyph substitution was successful for both fonts.

This is XeTeX, Version 3.1415926-2.2-0.9995.2 (TeX Live 2009/Debian)

I deviated from your example only in not using the xelibertine package
(which is not available anymore, since it was superseded by the
libertine package).
