Two possibilities:
1) shop_price is defined as text, but numeric
2) your client is broken
You have to tell us which one (possibly both) is true.
If your truly issue "sort by shop_price" instead of "order by shop_price"
you are not speaking SQL directly so any solutions are going to be
client-specific and you should ask them. PostgreSQL will order this
properly if provided a correct query and shop_price is numeric in nature.
If you need to alter the field type you can use the "Alter Table" command;
it is well documented. I will require a full table rewrite so depending on
the table size it could take a while.
