I think this is the answer :-)
======================================================================
Objective Caml version 3.08.3
# 1_;;
- : int = 1
# 1_2_3;;
- : int = 123
etc.
======================================================================
See "integer literals" in the manual :

But I agree with you: this is wierd and almost a bug...
