[Emacs-orgmode] How to sort by tags

[Pete Phillips]

Morning all.

I use the org-agenda facility to set up groups of tags so that I can hit
'C-c a h' to produce an agenda buffer with all my Home life tags:

-------------------------------------------------------------------------
Headlines with TAGS match: 
+LaptopH|PhoneH|Home|Sofa|ComputerH|WaitingH|Shopping|DIY
Press `C-u r' to search again with new search string
  TODO:       Cut Lawns                              :DIY:
  TODO:       Revise - top and tail Job Description A4C !!! :LaptopH:
  TODO:       Buy USB 2.0 card for Computer (£19 Opal) :Shopping:
  TODO:       Rake Moss                              :DIY:
  TODO:       Prices for USB/Firewire disk for home backup (Opal £26 enclosure, 
£59 120Gb) :Shopping:
-------------------------------------------------------------------------

etc etc

I'd like to be able to sort and group by tags, so that, for example, all
the DIY jobs would print together. Some sort of optional separator
between groups would also be nice ..... :-)  Eg:



-------------------------------------------------------------------------
__DIY__
  TODO:       Cut Lawns                              :DIY:
  TODO:       Rake Moss                              :DIY:

__LaptopH__
  TODO:       Revise - top and tail Job Description A4C !!! :LaptopH:

__Shopping__
  TODO:       Buy USB 2.0 card for Computer (£19 Opal) :Shopping:
  TODO:       Prices for USB/Firewire disk for home backup (Opal £26 enclosure, 
£59 120Gb) :Shopping:
-------------------------------------------------------------------------

I can't seem to find any functionality of this type. Have I missed
something obvious ?
