Rails - Oct 2005 - REXML::XPath results out of sort order ?

Hello,
I need a reality check here,
given this xml : http://rafb.net/paste/results/iziEQI77.html

this test :
  mi = XPath.match(@xml,
''//HomesiteTree/Builder/Division/Workflow/Milestone'')
  assert_equal ''10'',
mi[0].elements[''MsMilestoneId''].text

fails with :
 2) Failure:
test_enrollmentMilestones(EnrollmentTest)
[C:/ruby/dev/BuildviewExtractor/test/functional/enrollment_test.rb:64]:
<"10"> expected but was
<"80">.


Is XPath.match returning results out of order ?

Am I missing something ?

Thanks for your advice.
