You have to select pdf 1.4 or higher.  And before going to print you 
need to flatten the file somehow. Some printers will do this for 
you as part of prepress. But for those that insist on PDF/x1a:2001
(essentially a restricted form of pdf 1.3) my strategy is to print 
to file in Acrobat reader yielding a flattened Postscript file and 
then convert that file back to pdf.

Specifically LSI wants a flattened file but 360 Digital Books will 
still accept a pdf 1.5 file.  

It appears that some future version of Scribus will produce a pdf to 
the more restrictive PDF/X1a standard but it is unclear whether 
e.g. transparencies will be converted properly or just changed to 
100% opaque.
