ur right, for some , dont know what, i thought it as an int field, i now also find out that it can hold letters as well as numbers, so i guess that theory out the window.

It looks like you are ordering by text rather than a number.
If you need to convert text to a number it can be done like so:
cast('123' AS int4)
so for ordering the query might look like:
select * from tbl order by CAST(text_field AS int4);
