Thanks for the reply. Seems we're using the same libtiff version.

Don't know if this helps, but on our systems that haven't been upgraded
yet (ie are still on IM 6.2.4 with compression working), I notice that
identify gives the following instead:
TIF* TIFF rw+ Tagged Image File Format (42)
TIFF* TIFF rw+ Tagged Image File Format (42)
Appreciating the attempts to help resolve...

Works for us:
convert logo: -compress jpeg logo.tif
tiffinfo logo.tif
...
Compression Scheme: JPEG
Type
identify -list format
which version of TIFF are you using? We get
TIFF* TIFF rw+ Tagged Image File Format (LIBTIFF, Version
3.8.2)
Its possible your version of TIFF does not have JPEG compression
enabled.
ImageMagick checks to see if the compression is supported. If its not,
it resets it to 'none'.
