I'm not at all familiar with the Algerian/Tunisian dialect, so this is just a guess, really. "Amaken" is not just Libyan, but the standard Arabic word for "places". Since the Algerian and Tunisian dialects are occasionally influenced by the French language, this may be the "pluralised Arabicised" version of the French "place" (place --> blass (sing) --> blais (pl) ). This would be an irregular plural form, which is quite common in Arabic(as in "makaan--> amaken").
However, since you're translating that from Swedish into Danish, I think there is no need for you to translate it at all, you can just leave it as it is, can't you?

in Arabic: بلايس (if what I\'m saying is correct)

I just received confirmation from an Algerian friend that they use \"place\" (pronounced \"plass\" as in the French, or \"blass\") for \"place\". The plural they use is \"blassat\" or \"blais\".
