(Inventing new functionality rarely works.)

  <xsl:value-of select="x[$col_width]"/>

Extracts the string value of element "x", whose position is equal to
$col_width variable. If I understood you correctly, you want to extract the
value of variable $x*. You can't do this with vanilla XSLT, you need to use
variable or use another approach. You can, e.g., declare

<xsl:variable name="columns" select="document('')/*/x:columns"/>
<x:columns>
  <column>10</column>
  <column>100</column>
  <column>151</column>
</x:columns>

as top-level elements and in your template use

<xsl:value-of select="$columns/*[$col_width]"/>
