There are different approaches. The easiest would be to make a button that,
when pressed, populates a fourth field that can then be sorted.
Here's an approach that doesn't require two steps, but it does assume that
"@@" is reserved:
\define sortus()
<$vars lb="[[" rb="]]">
<$list filter="[has[fa]]">
<$list
filter="[<currentTiddler>addprefix[@@]addprefix{!!fc}addprefix{!!fb}addprefix{!!fa}addprefix<lb>addsuffix<rb>]"/>
</$list>
</$vars>
\end
<$wikify text=<<sortus>> name="ready2sort">
<$list filter="[enlist<ready2sort>sort[]]" variable="sorted">
<$list filter="[<sorted>split[@@]rest[]]"/>
</$list>
</$wikify>
