Pop text in front of that first value and it works:
template1=# select text '##10############--------####79909999'
template1=# as "sortfield"
template1-# union
template1-# select '###1############--------####79909999'
template1-# order by sortfield; sortfield
--------------------------------------###1############--------####79909999##10############--------####79909999
(2 rows)
