An elegant solution to this problem is to not use 'cron' at all; use
'at'. 'at' the script to run the first time at the appropriate time
on the first Tuesday that you want. Have the script run, and if all
goes well, make the last line of the script be:

at now + 21 days 'scriptnamehere'

I suppose you mean
echo 'scriptnamehere' | at now + 21 days
or something similar.
like:
at now +21 days <<-!
'scriptnamehere'
!

Why not using "$0" rather that 'scriptnamehere'?

"at" reads the command(s) to execute from stdin or from a file if
you specify such a file.
