Why has the mainkey SC if signing is not used? Are there some compatibility reasons?

I am working on some new keypairs with backwards compatibility, pls see this thread:
Some corporate partners are still using older versions of Symantec's PGP with WinXP, mostly for intranet. Problems with signing keys are known, sometimes it works, sometimes not. It is very difficult to rate compatibility because Symantec's enterprise support (!) isn't be able to send me old PGP versions for testing.
Compatibility seems to be depending on order of subkey creation:
If encryption key is latest, it is working.
If signing key is latest, mostly it is not working.
DSA signing keys are only accepted if max 2048 bit!?
If signing key is not the latest one and will be exchanged, it steps to last position => mostly not working.
And so on...
Best combination found so far:

Is there any possibility to change order of subkeys in keypair?
Thanks for any hint, regards, Chris
