Script works very smoothly. Thanks!
There were 2 things that needed adjustment. First one was the offset for the donation gump. The fix is posted by another on the previous page in the replies, so I won't repeat it here.
My character had blacksmithing skill, so the vendor interface inserts getting Bulk Order Deeds, and now, Bribes. I fixed this by removing the blacksmith skill from my character. After I am done I will restore it. I suppose the script could be adjusted to detect and compensate for the different menu, but my fix worked for me. I do not have a legendary blacksmith with whom I make the donations (my skill is merely .1 to acquire BODS), but another may run into the same issue and this hint may work for them.
