Sorry E&C, but the idea of a rail-armed Tigershark variant was in the Tau list before it was in the Taros Campaign - and if the crap they put in about the Tau fleet is anything to go by, the book is not exactly perfect (think of it as an Ordo Xenos record of the event, which may or may not conflict with alternate sources...)
But the Taros Campaign is not written from any kind of subjective perspective, it is fully objective on almost every single page except those that print 'excepts' from officer's logs etc.
Taros is the first recorded use of the Rail-Shark, and it is stated as being a very new ship developed in direct response to previous dealings with Imperial Titans.
This is cannon-fluff, whether that variant was in any armylist before the release of the Taros book doesn't really matter... it doesn't affect the background one jot.
And the idea of the alternate HH turrets being prior to the IC option makes sense when you consider that accroding to the SG PDF for the CPF, the Demiurg sold ion cannon tech to the Tau. Early HHs could well have been armed with these other configurations, but to an Imperial force on Taros they could have been considered as 'new'!
