If I create 2 files hat.tif and lady.tif with transparency in photoshop and
then use these commands:

convert hat.tif newhat.tif
convert lady.tif newlady.tif

then the tranparency is disappeared from these files
and the maks used to create tranparency is now appearing
as an extra channel in photoshops channels palette.
In hat.tif and lady.tif the transparency mask was not present
in channels palette

the test files is found here:

Unfortunately we cannot reproduce the problem you posted. The resulting TIF image remains transparent for us. We're using ImageMagick 6.4.0-4, the latest release.
