Help with context use of $s_date_order

I think $s_date_order is used in manage_proj_ver_edit_page.php, but I´m 
not sure what it means.

All languages I can "understand" (and myself also for spanish) translate 
"Order by date" (Orden por Fecha), but this makes no sense at all ... 
which means that date in context?

Regards!
