I modified the scheme and the function. I think, that these 2 if-s just complicate the code for comprehension: we have 3 cases,
for each of them we should return the appropriate value.
Here is my variant of the function, including the fix, that you suggested:
(defun org-read-prop (prop)
"Convert the string property PROP to a number if appropriate.
Otherwise if prop looks like a list (meaning it starts with a
'(') then read it as lisp, otherwise return it unmodified as a
string."
(if (and (stringp prop) (not (equal prop "")))
(let ((out (string-to-number prop)))
(if (equal out 0)
(cond
((or
(equal "(" (substring prop 0 1))
(equal "'" (substring prop 0 1)))
(condition-case nil
(read prop)
(error prop)))
((string-match "^\\(+0\\|-0\\|0\\)$" prop)
0)
(t
(set-text-properties 0 (length prop) nil prop)
prop))
out))
prop))
All the tests work fine with the new version.
When I tried
(org-read-prop "(1 2 3))") -> (1 2 3)
It gave me (1 2 3), ignoring the last ')'. Seems to be the read function bug.
At last I got rid of these nasty little squares on the scheme :)
