Remember that at present what you are actually sending to the mapserver is
a regular expression. I've not yet changed mapserver to allow string and logical
expression queries via itemquery. That being said, ()'s are special characters
in a regex and therefore need to be escaped to work properly. Try this snippet
of code (it should work):

<select name="value" size="1">
  <option> Big Fork River
  <option value="Big Sioux River \(Medary Creek\)"> Big Sioux River (Medary Creek)
  <option value="Big Sioux River \(Pipestone\)"> Big Sioux River (Pipestone)
  <option> Blue Earth River
</select>

Note the escaped ()'s (i.e. the backslash). The same treatment is necessary with 
all regex special characters.

Mapserver users,

     I ran into a problem when I use the itemnquery on a shapefile
attributes.  The value of the attribute in a shapefile is Mississippi River
(Brainerd).  The itemnquery works on all the values that do not have a
perenthesis.  Do I have to put a special charcter in HTML file to identify
the perenthesis?  The other solution would be to edit the shapefile's
attributes.

Here is the HTML code:
<select name="value" size="1">
  <option> Big Fork River
  <option> Big Sioux River (Medary Creek)
  <option> Big Sioux River (Pipestone)
  <option> Blue Earth River
</select>

Thanks,
