For SQL select returning more than 1 value, how are they sorted when Id is GUID?

I'm wondering how MSSQL orders data that is returned from a query and the Id columns of the respective tables are all of type uniqueidentifier.

I'm using NHibernate GuidComb when creating all of the GUIDs and do things like:

Sheet sheet = sheetRepository.Get(_SheetGuid_); // has many lines items
IList<SheetLineItem> lineItems = sheet.LineItems;

I'm just trying to figure out how they'll be ordered when I do something like:

foreach (SheetLineItem lineItem in lineItems)

I can't see to find a good article on the way GUIDs are compared by SQL when being ordered, if that's what's happening.
