How to sort a list by byte-order for AWS-Calls

Having a look at http://ift.tt/1c0TI8Q

The following Name-Value Pairs:

Service=AWSECommerceService
Version=2011-08-01
AssociateTag=PutYourAssociateTagHere
Operation=ItemSearch
SearchIndex=Books
Keywords=harry+potter
Timestamp=2015-09-26T14:10:56.000Z
AWSAccessKeyId=123

The name-value pairs have been sorted according to byte-order

Should result in

AWSAccessKeyId=123
AssociateTag=PutYourAssociateTagHere
Keywords=harry%20potter
Operation=ItemSearch
SearchIndex=Books
Service=AWSECommerceService
Timestamp=2015-09-26T14%3A10%3A56.000Z
Version=2011-08-01

How to achieve this in R?

As far as i can tell they are sorted by their as.numeric(charToRaw(name)) values. If the first value is equal then they are sorted by the second one, then the third and so on.
