The variable org-export-with-sub-superscripts determines if '^' and '_' are
interpreted as super and subscripts during export.  When set to nil or "{}",
this works as intended when exporting a normal org file.

When using radio tables in a LaTeX file, this variable does not affect the
table translation.

To reproduce:

Start Emacs with -Q and run (require 'org) in the scratch buffer.

Create a simple .tex file that contains a radio table.  Ensure the radio table
contains underscores and carots.  Set the variable
org-export-with-sub-superscripts to nil.  (Alternatively, I will upload a test
file with appropriate file-local variables once this bug is accepted.)

Press M-S-: and evaluate the expression (orgtbl-mode).

Navigate to the table and press C-c C-c (if this doesn't work - it's
unreliable at times - do M-x orgtbl-send-table).  The radio table will be
filled in with \textsubscript{} and \textsuperscript{} directives.

This behavior is inconsistent with org's normal export mechanism, which does
respect the value of this variable.
