Try using the tracediff program (in the util directory, instructions on the website) to see where execution diverges between the simple CPU and the in order CPU. You'll want to use the Exec trace flag and turn of printing ticks with -ExecTicks. Putting a minus sign in front of a traceflag turns it off when it might have been implicitly turned on by something else. If your version of the code is older than Oct. 29th you might want to try using revision f299139501f7. That's immediately before a big change I made to how PCs are managed, and I may have broken InOrder. It's also possible this benchmark was just never run on it before and exposes some other issue.
