you can store the result in a variable and then sort it

B  B  B  B  B  B  B  <xsl:variable name="rows" as="element(tr)*">
B  B  B B B  B B B  B B B  <xsl:for-each-group
select="location[(xs:integer(class) eq 1) or
(xs:integer(class) eq 2)]" group-by="city">
B B B  B B B  B B B  B B B  B B B  <tr>
B B B  B B B  B B B  B B B  B B B  B B B  <td>1-2</td>
B B B  B B B  B B B  B B B  B B B  B B B  <td><xsl:value-of
select="format-number(sum(current-group()/value),'$###,###')"/></td>
B B B  B B B  B B B  B B B  B B B  </tr>
B B B  B B B  B B B  B B B  </xsl:for-each-group>
B B B  B B B  B B B  B B B  <xsl:for-each-group
select="location[(xs:integer(class) gt 2) and
(xs:integer(class) lt 7)]" group-by="city">
B B B  B B B  B B B  B B B  B B B  <tr>
B B B  B B B  B B B  B B B  B B B  B B B  <td>3-6</td>
B B B  B B B  B B B  B B B  B B B  B B B  <td><xsl:value-of
select="format-number(sum(current-group()/value),'$###,###')"/></td>
B B B  B B B  B B B  B B B  B B B  </tr>
B B B  B B B  B B B  B B B  </xsl:for-each-group>
B B B  B B B  B B B  B B B  <xsl:for-each-group
select="location[xs:integer(class) gt 6]"
group-by="city">
B B B  B B B  B B B  B B B  B B B  <tr>
B B B  B B B  B B B  B B B  B B B  B B B  <td>7-10</td>
B B B  B B B  B B B  B B B  B B B  B B B  <td><xsl:value-of
select="format-number(sum(current-group()/value),'$###,###')"/></td>
B B B  B B B  B B B  B B B  B B B  </tr>
B B B  B B B  B B B  B B B  </xsl:for-each-group>
B  B  B  B  B  B  B  </xsl:variable>
B  B  B  B  B  B  B  <xsl:perform-sort select="$rows">
B  B  B  B  B  B  B  B  B  <xsl:sort select="xs:decimal(replace(td[2], '[,$]',
''))" order="descending"/>
B  B  B  B  B  B  B  </xsl:perform-sort>

Having to do the replace after the formatting is probably not the right
approach but you could in the first step only store the number values
and in the second step sort and format if wanted.
