It is not fixed for me:
The version -12 fixes the kernel x.y.zfoo
But I have numbers after foo: x.y.zfooA where A is a number

Then with the new preinst:
$ cat  glibc_2.3.2.ds1-12.diff | grep kernel_rev
+    kernel_rev=$(uname -r | tr -- - . | cut -d. -f3 | tr -d
'[:alpha:]')
+    if [ "$kernel_rev" -ge 255 ]

It gives me: zA and it is incorrect

If sed can be use, it can be:
kernel_rev=$(uname -r | sed 's/[^\.]\+\.[^\.]\+\.\([^[:alpha:]]\).*/\1/')
