Several sample projects are included in the distribution of SCP. Each comes as one or more text files and as an SCP project file. Open a sample project (using File/Open) and select View/Project to look at the options that were used to create it. Examine the text files of the project and see how the options chosen for, say, the alphabet, would cause words to be selected for the vocabulary. By default a 'word' is one or more letters or other symbols taken from an alphabet of your choice, normally the hyphen or apostrophe also treated as if they were letters. The sorting order for words is determined by the order which letters appear in your alphabet and by the codes which are associated with each letter.
