Alex,

I'm not sure this is pertinent to your problem, but it is possible to 
support non-keyed multidimensional arrays using multiple delimiter 
characters.  Three-dimensional example:

on putValue thevalue, at theArray,xcoord,ycoord,zcoord,xdelim,ydelim,zdelim
    set the itemDelimiter to xdelim
    put item xcoord of theArray into firstLevel
    set the itemDelimiter to ydelim
    get item ycoord of firstLevel
    set the itemDelimiter to zdelim
    put theValue into item zcoord of it
    set the itemDelimiter to ydelim
    put it into item ycoord of firstLevel
    set the itemDelimiter to xdelim
    put firstLevel into item xcoord of theArray
end putValue

functyion getValue theArray,xcoord,ycoord,zcoord,xdelim,ydelim,zdelim
    set the itemDelimiter to xdelim
    get item xcoord of theArray
    set the itemDelimiter to ydelim
    get item ycoord of it
    set the itemDelimiter to zdelim
    return item zcoord of it
end getValue
