To clarify: the version strings used by EasyBuild for `icc` are the ones used in the 'official' versioning.
However, that's not what `--version` provides, see:

```
$ module load icc/2013.3.163
-bash-3.2$ icc --version
icc (ICC) 13.1.1 20130313
Copyright (C) 1985-2013 Intel Corporation.  All rights reserved.
```

If you need the `13.1.1` bit, as is the case for Rosetta (to specify as a make option), then you can use the `get_icc_version` function.
