Answer 1

How about this:
doc("c:\temp\temp.xml")/
<billSummary>
{
for $e in billSummary/*
order by local-name($e)
return $e
}
</billSummary>

Answer 2

Order by node names:
<billSummary>
{
for $i in /billSummary/*
order by $i/name()
return $i
}
</billSummary>
In case you want to group only items inside each bill, loop over all <billSummary/>-nodes:
for $bill in //billSummary
return
<billSummary>
{
for $item in $bill/*
order by $item/name()
return $item
}
</billSummary>
If you need to wrap some node around your answer, you should be able to do it yourself; your question does not contain the information necessary.
