I think counting the number of siblings should allow the output to be order
independent. The (untested!) condition for chapter 3 would be:
<when test="count(preceding-sibling::chapter) = 2">
If you don't like the zero-offset, then:
<when test="count(preceding-sibling::chapter | self::chapter) = 3">
However, maybe there's a better way. If the colour represents some aspect of
the chapters (introduction, topic-A, topic-B, etc..) rather than their
structural position (like with Zebra tables) then it might be better to mark
this within the DocBook (e.g., adding a custom role for the chapter) and base
the markup on the chapter's role, rather than hard-coding the chapter numbers
within your XSLT customisation layer. This would give you flexibility to
reorder the chapters, add new chapters, etc without having to alter your
stylesheets.
HTH,
Paul.
