I have this feeling I must be missing part of the problem, but why not
just add the variables (ie $groupa_count + $groupb_count) in the
value-of?  (see below)

If you want the sum for both groupa and groupb and then add those
together can't you simply use sum in a template that similar to the
"count" template you have?

 <xsl:variable name="total_count">
        <xsl:value-of select="$groupa_count + $groupb_count"/>
 </xsl:variable>

<!-- should probably do something with the variable here, but I'm not
sure what you want...perhaps just have the xsl:value-of
select="$groupa_count + $groub_count"? -->
