Sorting Problem

Currently I'm running PostgreSQL 7.2.3 and having a problem sorting.

I've got two colums of data, one Int4 one Varchar.

When I sort ASC on the varchar I get some strange results. Here a section of
data cut after running a sort. It starts with RM- then does RMT- Then goes
back for more RM-. I've checked for spaces or tabs or anything else odd and
cant find anything that would effect the sort.

63   RM-791
38   RM-AV2100
9   RM-PP401
10   RM-PP402
8   RM-PP404
3   RMT-D10
4   RMT-D108A
5   RMT-D109A
6   RMT-D116A
34   RMT-V402
40   RM-V10
41   RM-V11
45   RM-V12

Here's the sort string I'm using:

SELECT "remote_id", "remote_model" FROM "remote" ORDER BY "remote_model"
ASC;

Any idea or suggestions why it would do this ?
