I think I'll try option one - I'm a slow and clunky coder - I've written 
this which tests the next node for the telltale <brackets> and grabs the 
datestamp. It then renames the node with the datestamp at the beginning of 
the node name. 
The plan is to rename all the nodes with datestamps in the body of the 
text, then use Leo commands to sort the nodes then un-name them, if you see 
what I mean. I'll need to deal with the deadline datestamp - I'll think on 
that. If you see any obvious improvements do let me know.

p=p.moveToNext() # drop down to next node
separator='||' # make a separator
if '<' and '>' in p.b: # check to see if there is at least one likely 
datestamp
    i = p.b.find("<") #get the index of the beginning of datestamp
    j = p.b.find(">") # get the index of the end of the datestamp
    datestamp=p.b[(i+1):j]  # use indices to grab the date
    newhead=datestamp+separator+p.h #make a new header including the 
datestam and separator
    c.setHeadString(p,newhead) #write the new header.

Thanks for the encouragement - If I get a working solution I'll let you 
know!
