All you need is a form on your results page, something like this:

<form action="[process]" method=post>
<input type=hidden name=mv_todo value=return>
<input type=hidden name=mv_nextpage value=@@MV_PAGE@@>
<select name=sort_field onChange="this.form.submit()">
[loop arg="category manufacturer price"]
         <option value="[loop-code]"
         [selected name=sort_field value="[loop-code]"]> Sort by [loop-code]
[/loop]
</select>
<input type=submit value="Sort">
</form>

...then just ad the sort_field to your search:

[search-region
         more=1
         search="
                 co=1
                 op=em
                sf=shop
                 se=cookshop
                op=em
                sf=category
                 se=[scratch current_category]
                 tf=[value sort_field]
                 [if value sort_field eq price]to=n[/if]
                 ml=21"
]

Note that I kludged in numeric sorting for the price field only - the 
default sort type is alpha, I believe.
