Try:

<xsl:value-of select="/DOCUMENT/Image_A/IMG/@HEIGHT - /DOCUMENT/Image_B/IMG/@HEIGHT"/>

...which has the same effect as:

<xsl:value-of select="number(/DOCUMENT/Image_A/IMG/@HEIGHT) - number(/DOCUMENT/Image_B/IMG/@HEIGHT)"/>

Of course, MSXML 2.0 doesn't support number(). Hopefully you've read
http://www.netcrucible.com/xslt/msxml-faq.htm and aren't still using the
old syntax.
