I'm no expert at all at zsh-scripts but I think the problem is that
myfiles isn't an array anymore after the first iteration. I changed your
code to the following:

findfiles() {
    local myfiles myarg
    myfiles=( **/*$1* )
    for myarg; do
    print $myfiles

There are two little differences here. First of all, I didn't write '$@'
in the for-line. If you don't give an 'in x', for iterates over the
remaining arguments.

The second difference - and the more important one - is, that I put ()
around the rhs of the myfiles-assignment, to make sure to assign an
array to the variable myfiles. I think that was the catch. After this
modification, your script works fine :)
