Judging from a number of Postscript files on my hard disk, at least files
created by dvips have:

%%Page: x y

where x is the actual page number (not necessarily unique or increasing)
and   y is a sequential numbering of the pages (1, 2, 3, etc)

The total number of pages is given, for instance, by

%%Pages: 18
%%PageOrder: Ascend

in the header.

Cheers, Nicke
