dotplot question

Dear list,

I have a couple of questions related to dotplots and ranef:

1) Does anyone know how to order the distribution of a residuals in a 
dotplot:

dotplot(dotplot(ranef(model, postVar = TRUE)...

sometimes residuals are ordered but other times they are not.

2) Is it possible to organize these plots in a matrix (as par function 
does)? I have more than a random term... so would be useful to order 
theses plots in a matrix...

3) Is it possible to change the strip name of these plots?

Any clue about these questions will be appreciate.
Thank you in  advance!
