You can define the weights like this ...

order.i.want <- c(3, 6, 7, 4, 5, 2, 8, 9, 1, 10)
wts <- order(order.i.want)
dd.reorder <- reorder(dd, wts, mean)
plot(dd.reorder, main="ordered random dendrogram")

You should cc R-help on all communication ... that way other readers can
follow the thread, and you may get an answer much more quickly to your
query.
