The answer is here:

and in the (interactive "rP") specification:

,-------------------------------------------------------------------------
| ‘P’
|
|     The raw prefix argument. (Note that this ‘P’ is upper case.) No I/O.
|
| ‘r’
|
|     Point and the mark, as two numeric arguments, smallest first. This
|     is the only code letter that specifies two successive arguments
|     rather than one. No I/O.
`-------------------------------------------------------------------------

thus 

,---------------------------------------------------------
| (org-table-convert-region BEG0 END0 &optional SEPARATOR)
`---------------------------------------------------------

with C-u M-x org-table-convert-region should be e.g.

,----------------------------------------
| (org-table-convert-region 38  456 '(4))
`----------------------------------------

and C-u 3 M-x org-table-convert-region should be

,----------------------------------------
| (org-table-convert-region 38  456 3)
`----------------------------------------

but I checked with edebug, its actually 

,----------------------------------------
| (org-table-convert-region 38  456 nil)
`----------------------------------------

and "When nil, the command tries to be smart and figure out [itself]"

So the problem seems to be that 'C-u 3' doesn't work as expected in my
case. Could you check if it works for you?
