Perfect. The solution to my problem looks like this:

ext_tables.php:
if (TYPO3_MODE == 'BE') {
 
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typo3/backend.php']['constructPostProcess'][] 
= 'EXT:my_skin/classes/class.tx_myskin_hook.php:tx_myskin_hook->addStyles';
}

classes/class.tx_myskin_hook.php:
class tx_myskin_hook {
   public function addStyles($conf, $pObj) {
     $pageRenderer = $GLOBALS['TBE_TEMPLATE']->getPageRenderer();
     $cssPath = t3lib_extMgm::extRelPath('my_skin') . 'res/css/';
     $extConf = 
unserialize($GLOBALS['TYPO3_CONF_VARS']['EXT']['extConf']['my_skin']);
     $allowedGroups = t3lib_div::trimExplode(',', $extConf['beGroups'], 
TRUE);
     $userGroups = t3lib_div::trimExplode(',', 
$GLOBALS['BE_USER']->user['usergroup']);
     $matchingGroups = array_intersect($userGroups, $allowedGroups);
     if (!empty($matchingGroups)) {
       $pageRenderer->addCssFile($cssPath . 'my_skin.css');
     }
   }
}

It seems, the BE code structure is much cleaner than I expected. Good work!
