I have the same type of problem on Ubuntu 9.04 (64-bit) with the Ubuntu OpenOffice (3.0.1). Upon PDF export, some numeric characters in Math equations are replaced, especially in sub and superscripts.
Using a colleague's OpenOffice 3.1.0 on Windows XP, no PDF export problem was encountered and the math looks normal. For now, I will use this method to generate PDF, while waiting that hopefully the problem will be solved in Ubuntu OpenOffice 3.1.1 which appears to be included in the upcoming Ubuntu 9.10.
While looking for a solution to the problem, I had the impression that it is mostly 64-bit Linux users who encounter this problem.
