[xsl] order-by: char or int?

["TP" <tpass001@xxxxxxxxxxx>]

My xsl:for-each looks like this

<xsl:for-each select="PrintCabinate/item" order-by="+ Name;currentPage">
----
</xsl:for-each

Now while sorting it, it assumes that currentPage is char, so it places 11
before 7 for eg, whereas 7 shud be b4 11.

is there a way to convert currentPage to int for the purpose of sorting.

Thanks in advance.
