In such cases I prefer specifying the complete paths in the script so as
not to get lost. If the script needs to work in a specific directory of
root I'll put:
cd /root/dir/dir1
or something like:
cd /home/username/dir
and so on (adding whatever error recovery is needed).
If I need to source a file I just type in the complete path name. It's
a one time bother and the executing shell doesn't care and as the script
gets more complex it's much easier to keep one's bearings on where the
script is working at various points.
As I see it, relative paths are more for interactive shell use.
