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.
