a single string selected from SQL cannot exceed 2000 bytes in 7.x and 4000 bytes in 8.x.

in plsql you can make strings upto 32k. these strings cannot be select'ed in SQL queries. those strings are limited to 2000/4000 characters.

when you remove the order by -- you get back some rows (that are less then 2000/4000 bytes) until you hit a row that exceeds this limit.
