One technique photographers use when making copies of "flat" images
(such as paintings or old pictures) is to polarize the light
illuminating the subject (in your case, the original photograph.
If you can polarize the light used by the scanner into the proper
orientation, "bumpy" reflections can be minimized.  Even just
a sheet of polaroid material over the scanner may help.

Of course, I could be wrong...
