You want:
<xsl:value-of select="preceding-sibling::PRODUCT/SKU"/>
Explanation:
/SKU (elements named SKU that are children of...)
PRODUCT (PRODUCT elements...)
preceding-sibling:: (from among all nodes that are preceding
siblings of the current node)
For clarity you might want to put [1] after PRODUCT so you don't get the
SKUs of *all* preceding-sibling PRODUCTs. However the fact that you are
using xsl:value-of means you're only going to look at the string-value of
the first node in that set, which will happen to be the one you want.
