Try making the sorting case insensitive i.e

(not tested!)
<xsl:variable name="uppercase" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/>
<xsl:variable name="lowercase" select="'abcdefghijklmnopqrstuvwxyz'"/>

......
<xsl:sort order="ascending" select="translate(Synonym, $lowercase, $uppercase)"/>
......

Here's what the specification says about sorting: case-order has the value upper-first or lower-first; this applies when data-type="text", and specifies that upper-case letters should sort before lower-case letters or vice-versa respectively. For example, if lang="en", then A a B b C c are sorted with case-order="upper-first" and a A b B c C are sorted with case-order="lower-first". The default value is language dependent.
