How do I sort by descending order (reverse order)?  Also, what’s the difference between sort by modified date and sort by last activation?  They both seem to do the same thing… a newest file gets moved to the first tab position.
PS:  Did I setup my settings correctly?  I was just getting how to get it working to sort by modified date.
{
	// Automatically sort tabs when loading or saving a file.
	"sort_on_load_save" : true,
	// Command to use for automatic sort.
	// If not specified, it use the last used sorting command
	// Available defaults command are:
	// 	sort_tabs_by_name
	// 	sort_tabs_by_file_path
	// 	sort_tabs_by_type
	"sort_tabs_by_date" : true,
	// 	sort_tabs_by_last_activation
	"sort_on_load_save_command" : "sort_tabs_by_date"
}
