XSL sorting version number strings

I am not that familiar with XML or XSL and I am trying to sort application version number strings in an XML file that my team uses for application installations on our Linux servers. I have tried the xsl:data-type=number, but that doesn't work. The output of the XML file is exactly what the XML file has and I would like to sort it by the number value.

Below is the some of the output from the XML file.

<?xml version="1.0"?>

<?xml-stylesheet type="text/xsl" href="releases.xsl"?>

<applications>

  <application>

    <name>AAT</name>

    <versions>

      <version>4.0.1.10</version>

      <version>4.0.1.13</version>

      <version>4.0.1.14</version>

      <version>4.0.1.15</version>

      <version>4.0.1.16</version>

      <version>4.0.1.8</version>

      <version>4.0.1.9</version>

      <version>4.0.3.1</version>

      <version>4.0.3.10</version>

      <version>4.0.3.11</version>

      <version>4.0.3.12</version>

      <version>4.0.3.13</version>

      <version>4.0.3.14</version>

      <version>4.0.3.15</version>

      <version>4.0.3.16</version>

      <version>4.0.3.17</version>

      <version>4.0.3.2</version>

      <version>4.0.3.3</version>

      <version>4.0.3.8</version>

      <version>4.0.3.9</version>

    </versions>

</applications>

Here is the XSL file.
