I'm a little confused about what the real problem is here. cp should be
able to cope with a file that is marked as read-only. Is this saying the
target already exists and can't be written to? Or is it unable to read
from the source? Is the source locked?

Worst case you can implement a custom "unpack" function for your
clearcase fetcher like git does and in there, exclude the problematic
files.
