It;s possible that 'standard' means it will sort according to 'the unicode standard' - see this page for a short description of how finder sorts it's output. From the page referenced:
The Unicode standard
Technically speaking, Finder sorting is based on the Unicode Collation Algorithm, defined by the Unicode Consortium. This standard provides a complete and unambiguous sort ordering for all Unicode characters, and is available on the Unicode Consortium website. Other operating systems or applications may use different rules that can make the same list of items sort in a different way.
There are different ways to sort alpabets - english is one order, but there are not only other language specific orderings, but 'generic' sort orders and many others. 'Standard' may refer to the ISO14651 standard sort order. If you really want to dive in, read this.
