Differences between Scottish and British Uniforms in WWII

Hey everyone, i have a box of 1/72 Revell Figures. On the box it says they are Scottish Infantry. It includes some figures in trenchcoats(wintercoats, whatever you call them) and some figures in desert uniforms. To me the British and scottish desert uniforms look the same, and they have the same weapons and are from basicaly the same area. Excuse me for my lack of the knowledge of Britain and Scotland, but do they have the same uniforms? The reason i want to know is because i want to build a diorama with a british matilda tank and want to add the figures to the diorama. Can i use the Scottish infantry in place of the British infantry? Thanks for your help, cause this confusing me. i may just have my armies mixed up or something. Here are some pictures of the box and one of the figures i painted. Thanks again for your help.
