I get the same result with
C:\GDAL_dev>gdaltransform -s_srs EPSG:27700 -t_srs EPSG:4326
0 0
-7.55729138544866 49.7667307394399 50.4807807933539

Conclusion: gdaltransform does not understand OSGB grid references. What made
you to believe it would? I could not find anything suggesting that from the GDAL
documents.
