this only works for changes done with with the TCEmain. eg. if a BE-User 
changes (insert,update,delete) a record

in a scheduler-task (or FE-Plugin) there is no TCEmain,
as there is no BE-user: no FE-Plugin and no scheduler-task can change 
data with TCEmain (design-flaw?), so no automatic clearing of caches.
( I do changes to the database just with 
$GLOBALS['TYPO3_DB']->exec_...() which are available in every mode )

really?
no documentation found for this vale

the explicit PHP-equivalent would be:
$TCE->clear_cacheCmd('all'); or $TCE->clear_cacheCmd('temp_CACHED');
or $TCE->clear_cache($table,$uidList);

but: no BE-User -> not available
