For the records, TM_SELECTION follows the selection string syntax 
documented here: 
http://manual.textmate.org/references.html#selection-string

For example with multiple selections or columnar selections, you will 
see & and x in the string, and with “freehanded” placement of caret 
(e.g. option click past end of line) you will see + (which can also 
occur for column selections).

I think a regexp like this can be used for a simple parser:

     
/^(\d+)(?::(\d+))?(?:\+\d+)?(-|x)(\d+)(?::(\d+))?(?:\+\d+)?(?:&.*)?$/

	$1 = from line
	$2 = from column
	$3 = - or x indicating regular or columnar selection
	$4 = to line
	$5 = to column

I didn’t capture the “past EOL offsets”.
