You don't need to cast $count to a number, it will be done automatically for you; then again, with XPath 2.0 you need to start being more careful about the data types, so I suppose it's a good habit to have.

  <tr>
    <xsl:attribute name="style">
      <xsl:text>background-color: </xsl:text>
      <xsl:choose>
        <xsl:when test="$count mod 2 = 0">#FFFFFF</xsl:when>
        <xsl:otherwise>#E7EEFF</xsl:otherwise>
      </xsl:choose>
      <xsl:text>;</xsl:text>
    </xsl:attribute>
    <td class="fieldInfo">
      <xsl:value-of select="substring(LineItemName,1,45)"/>
    </td>
  </tr>
