The reason it doesn't work is because when you put [[MySingleWordTag]] in
tags, TW strips off the [[ and ]], so your text no longer matches.
The following worked in my tests. It uses the filter run evaluation to
determine if braces need to be added, only adding them if there is more
than one word.
<$vars myfilter="[split[ ]count[]compare:integer:eq[1]]" lf="[[" rt="]]" >
<$select field='tags'>
<$list
filter='[_object_type[location]!title<currentTiddler>!tag<currentTiddler>]'>
<option value={{{ [<currentTiddler>filter<myfilter>]
[<currentTiddler>addprefix<lf>addsuffix<rt>]+[first[]] }}}><$view
field='title'/></option>
</$list></$select>
</$vars>
