I assume that you mean "auto eth3.77" not "auto eth3.107".

Otherwise

auto eth3.107

iface eth3.77 inet static
address 10.0.5.15
netmask 255.255.255.0

iface eth3.77 inet static
address 10.0.5.16
netmask 255.255.255.0

works for me in the form of

allow-auto eth0.9

iface eth0.9 inet static
address 192.168.1.119
netmask 255.255.255.0
gateway 192.168.1.1

iface eth0.9 inet static
address 192.168.1.199
netmask 255.255.255.0

You definitely need an "iface eth0.9 inet static" for each ip address
assignment.
