Works for me. 
perl -e 'my $x=q|v09.11-e020|;$x =~  m/^v[0-9][0-9]\.[0-9][0-9]-[a-z][
+0-9][0-9][0-9]/ and print " match\n"'
#Prints ' match'

You may want to make the regex somewhat shorter: 
 m/^v\d{2}\.\d{2}-[a-z]\d{3}/

     Theory is when you know something, but it doesn't work.
    Practice is when something works, but you don't know why it works.
    Programmers combine Theory and Practice: Nothing works and they don't know why.         -Anonymous
