In 2.0 you can write

<xsl:variable name="p" select="index-of(('undelivered', 'inprogress',
'delivered', 'escalated'), status)"/>
<span style="color:{('#ff0000', '#33cc33', '#33cc33', '#33cc33')[$p]}"/>

One way I sometimes do it in 1.0 is:

<xsl:template match="status[.='undelivered']"
mode="color">#ff0000</xsl:template>
<xsl:template match="status[.='inprogress']"
mode="color">#33cc33</xsl:template>
<xsl:template match="status[.='delivered']"
mode="color">#33cc33</xsl:template>
<xsl:template match="status[.='escalated']"
mode="color">#33cc33</xsl:template>

<span>
  <xsl:attribute name="style">
    <xsl:text>color:</xsl:text>
    <xsl:apply-templates select="status" mode="color"/>
  </xsl:attribute>
</span>
