Do you want to match the code using $msg and $msgType as in \administrator\components\com_installer\models\install.php?

		// Install the package.
		if (!$installer->install($package['dir']))
		{
			// There was an error installing the package.
			$msg = JText::sprintf('COM_INSTALLER_INSTALL_ERROR', JText::_('COM_INSTALLER_TYPE_TYPE_' . strtoupper($package['type'])));
			$result = false;
			$msgType = 'error';
		}
		else
		{
			// Package installed successfully.
			$msg = JText::sprintf('COM_INSTALLER_INSTALL_SUCCESS', JText::_('COM_INSTALLER_TYPE_TYPE_' . strtoupper($package['type'])));
			$result = true;
			$msgType = 'message';
		}

From my point of view my code is clearer and it's approved already.
We have already a successful test and I don't want to waste time of valuable testers.
But like always: Take over if you want to and I close here. I don't want to waste too much time with a small change like this.

I only wait for a second test to merge.
