  Language and script are selected the same way as features, with the
keys Language and Script respectively.  You thus have several commands
at your disposal, either (untested code)

	\fontspec{FaliscanCDS}
	\addfontfeatures{Script=Old Italic,Language=Faliscan}

or

	\fontspec[Script=Old Italic,Language=Faliscan]{FaliscanCDS}

or -- the best choice in an actual document

	\newfontfamily\olditalicfont[Script=Old Italic,Language=Faliscan]{FaliscanCDS}

and use then \olditalicfont for your text in Faliscan.

  These commands of course need the Faliscan language to be defined with
\newfontlanguage.

	Best,
