The XPath spec contains a String Functions section that you will find 
helpful. http://www.w3.org/TR/xpath#section-String-Functions

Yes, there is a string-length function.

Something like this (untested code):

<xsl:variable name="num" select="'21'"/> <!-- for example -->
<xsl:variable name="lastChar" select="substring($num,string-length($num))"/>
<xsl:variable name="formattedNum">
  <xsl:value-of select="$num"/>
  <xsl:choose>
    <xsl:when test="$lastChar='1'">st</xsl:when>
    <xsl:when test="$lastChar='2'">nd</xsl:when>
    <xsl:when test="$lastChar='3'">rd</xsl:when>
    <xsl:when test="not(translate($lastChar,'4567890',''))">th</xsl:when>
  </xsl:choose>
</xsl:variable>
<xsl:value-of select="concat('unformatted: ',$num,'&#10;formatted: ',$formattedNum)"/>
