preserve-order attribute is ignored with Surefire plugin 2.8.1

This is a clone of http://jira.opensymphony.com/browse/TESTNG-477 , which I'm pasting here:

"preserve-order" attribute is completely ignored with Surefire plugin 2.8.1 and TestNG 5.14.1.
It looks like the test classes are executed in some random order instead of the one specified in testng.xml.
This execution order is correct with Surefire plugin 2.5.

Here is the file:
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="Component Tests" verbose="2" annotations="JDK">
<test name="My Tests" preserve-order="true" >
<classes>
<class name="server.InstallTest" />
<class name="server.ATest" />
<class name="server.SCHTest" />
<class name="server.PRGTest" />
<class name="server.SIBBTest" />
<class name="server.EDNTest" />
<class name="server.PPVTest" />
</classes>
</test>
</suite>
