Sorry, the solution was in front of us all the time. My 30-metric-aliases.conf was from a clean install of Trusty and is presumabley unmodified by tex-gyre or Latex as I didn't install them, even though it contains some references to tex-gyre as a lower priority match. As per comment #24 the Trusty update that you have installed only contains a fix to stop aliasing TeX Gyre Termes to Times. As Leopoldo said in comment #10, the file attached to comment #10 renders with Tex Gyre Heros (it's a substitute of Helvetica). I've just checked the file you attached to comment #12 and it also uses Helvetica.
Bug 1379375 contains a solution. I have combined this with the patch referenced in comment #24 (from http://cgit.freedesktop.org/fontconfig/commit/?id=c6aa4d4bfcbed14f39d070fe7ef90a4b74642ee7 ) and attached a new 30-metric-aliases.conf file. As I am not affected by this bug, am not a programmer, and am not an Ubuntu team member I will be unable to assist further with this bug. I have, however, subscribed Canonical's Iain Lane to bug 1379375.
