I'm no expert on this, but I think your only really sensible option would be to obtain an export to DOCX from your customer and translate that.  I know a *.pages file is essentially a zip, so you can unzip it gate some interesting benefits, but I don't think a file you can translate is one of them.  I believe older versions used to contain a PDF for previewing, and maybe saving with Word compatibility might have added a DOC (I'm not 100% on this), but neither are really helpful since translating them can't be repacked to update the Pages file.

I think the best process is probably this:

• Convert the Pages document to a DOCX file through Pages itself, if you have access to a Mac or iPad with Pages installed. This ensures the file is properly formatted for Word.
• Translate the DOCX file using your preferred translation method or software.
• Open the translated DOCX file in Pages. Pages is capable of opening DOCX files directly. You can then save the document as a new Pages file.

Not perfect, but probably the best solution.  I guess anyone handling customers who use this format a lot should probably invest in a MAC and charge for the necessary DTP.

Just an aside, but I often wonder about MAC.  Whilst only a few CAT tools will run on it, I'm not aware of any that can handle their file formats.  I always find that surprising as you'd think, if there really a serious demand for this, someone would have done it by now!!

Thank you for your reply and thoughts. 
I succedded to save the files to a lower version (09) and exported the XML file from the archive. I opened it in Trados without any issues. So I will continue with the translation of this file without conversion.

P.S. This is strange indeed - so many translation and localization needs in USA and no CAT tool is able to process .pages?! Maybe the clients do not provide the text in .pages but in DOCX format?!
