That is weird, not what I'd expect at all. I've duplicated in:

VIM - Vi IMproved 7.3 (2010 Aug 15, compiled Jun 6 2012 07:36:47)
MS-Windows 32-bit GUI version with OLE support
Included patches: 1-540
Compiled by digitectNO@SPAMdancingpaper.com
Huge version with GUI.

The BufEnter event is also too early.

I wonder if the new QuitPre autocmd event introduced in 7.3.544 would allow this to work. I'm not 100% sure you could reliably detect a :tabclose event though using it (maybe I'll try later at home where I compile my own Vim).
