Without question, VSO is the most frequent order (also judged as "most common" by speakers). But other orders are also possible without being ungrammatical.
Analyzing a corpus of various text types (spoken discourse, stories, written texts), Aoto (2002: 85–87) finds that VSO represents 85% of the cases in spoken language. However, in written texts, especially news, 75% of the sentences show an SVO order.
Value 2 comment: In SVO order, the subject is focused (e.g. answer to a question).
Especially in written texts, word-order is beeing influenced by English. SVO also occurs frequently in sentences beginning with adverbs (adjuncts).
Value 4 comment: VOS is not ungrammatical (I have checked it by elicitation) but it does not occur in my own data.
