I disbelieve. The -perm option allows you to specify a permissions
list to match. Execute is 1, write is 2, read is 4. Owner is the first
digit, group is the second and other the third. Leading zeros are
optional.

$ touch it
$ chmod 000 it
$ chmod o+w it
$ find . -name it -perm +002 -ls

$ find . -name it -perm +200 -ls
$
$ chmod 007 it
$ find . -name it -perm +002 -ls
825789    0 -------rwx   1 ratinox  ratinox         0 Nov 15 20:27 ./it
$ chmod 700 it
$ find . -name it -perm +002 -ls
$
