It is not a bug, but it is a difference.

MICROSOFT OFFICE BEHAVIOR

I just opened that document, with name PERENNIAL.doc successfully in Microsoft 
Word 2013 Preview (x64 to my surprise) and in Word 2010.  

In Word 2007 SP3, there were reports that the attempt to treat the document as 
WordPerfect (which also used the .DOC extension) failed, but then it opened 
just fine in "Compatibility Mode."  

Word 2003 reported that it could not handle the file with a couple of 
converters and said that another converter was needed.  (That had me thinking 
that I may not have installed the Compatibility Pack on this one.)  I selected 
OK for download and installation of a needed converter.  It finally failed 
attempting to open the file as text.
   I confirmed that the Word 2003 Compatibility Pack (which supports OOXML) was 
installed.  But apparently the Word 2003 sniffer for file format doesn't detect 
OOXML and use the correct converter when loading a .DOC file.

THE DIFFERENCE

Microsoft Office does not rely on file extensions exclusively.  It also sniffs 
the file to determine what the real format is, if possible.  (The OOXML 
standard does not even specify file extensions.)  In the case of Word 2007, 
Word 2010, and Word 2013 Preview, this works fine.

THE IMPROVEMENT FOR AOOi

It would be useful to have the AOOi code that opens non-ODF documents (and ODF 
file extensions for that matter) to sniff the document and determine the actual 
case better than it does.

PS: e-letter may be pleased to learn that Office 2013 Preview appears to 
produce and consume ODF 1.2 documents quite nicely.  This includes Excel now 
using OpenFormula when saving a document as ODF, and the few tests I've run 
open beautifully in LibreOffice Calc. (I haven't tried AOOi Calc 
interoperability testing yet.  That's done on a different computer.)

One thing that's been pointed out is that the file has the wrong 
extension.  Change it back to DOCX and it works fine.  When does someone 
changing a file extension become a bug in AOo?
